• Debugging in Maven?

  - by aduric

  Is it possible to launch a debugger such as jdb from maven? I have a pom.xml file that compiles the project successfully. However, the program hangs somewhere and I would really like to launch jdb or an equivalent debugger to see what's happening. I compile using mvn compile and launch using: mvn exec:java -Dexec.mainClass="com.mycompany.app.App" I was expecting something like: mvn exec:jdb -Dexec.mainClass="com.mycompany.app.App" to launch the debugger but, as usual, my expectations are incongruent with maven's philosophy. Also, I couldn't find any documentation (on Maven's website or google) to describe how debugging works. I suspect that I have to use some plugin.

• What are the advantages of Maven when it comes to single man, educational projects

  - by Leron

  I've spend a few hours playing around with Maven + reading some stuff on the apache official site and also a few random googled articles. By this I mean that I really tried to find the answers myself - both by reading and by doing things on my own. Also maybe worth to mention that I installed the m2e plugin so most of the time I've tried things out from Eclipse and not using the command line too much. However aside from the generated project that for example prevent me from using the default package I didn't see that much of a difference with the standard way I've created my projects before try Maven. In fact I've almost decided to skip Maven for now and move on to the other technology I wanted to learn more in-depth - Hibernate, but when I start with opening the official page the first thing I've read was the recommendation to use Hibernate with Maven. That get me confused and made me taking a step back and trying once more to find what I'm obviously missing right now. As it's said in the maven.apache.. site, the true strength of Maven is shown when you work on large projects with other people, but I lack the option to see how Maven is really used in this scenario, still i think that there are maybe advantages even when it comes to working with small projects alone, but I really have difficulties to point them out. So what do you think are the advantages of Maven when it's used for small projects writing from a single person. What are the things that I should be aware of and try to exploit (I mean features offered by Maven) that can come in handy in this situations?

• Maven assembly - Error reading assemblies

• Maven Assembly Plugin - install the created assembly

  - by Walter White

  I have a project that simply consists of files. I want to package those files into a zip and store them in a maven repository. I have the assembly plugin configured to build the zip file and that part works just fine, but I cannot seem to figure out how to install the zip file? Also, if I want to use this assembly in another artifact, how would I do that? I am intending on calling dependency:unpack, but I don't have an artifact in the repository to unpack. How can I get a zip file to be in my repository so that I may re-use it in another artifact? parent pom <build> <plugins> <plugin> <!--<groupId>org.apache.maven.plugins</groupId>--> <artifactId>maven-assembly-plugin</artifactId> <version>2.2-beta-5</version> <configuration> <filters> <filter></filter> </filters> <descriptors> <descriptor>../packaging.xml</descriptor> </descriptors> </configuration> </plugin> </plugins> </build> Child POM <parent> <groupId>com. ... .virtualHost</groupId> <artifactId>pom</artifactId> <version>0.0.1</version> <relativePath>../pom.xml</relativePath> </parent> <name>Virtual Host - ***</name> <groupId>com. ... .virtualHost</groupId> <artifactId>***</artifactId> <version>0.0.1</version> <packaging>pom</packaging> I filtered the name out.

• Configuring hibernate.reveng.xml to detect a sequence PK generator with hibernate3-maven-plugin and

  - by mmm

  Hi, is there a way to configure hibernate3-maven-plugin so that a sequence generator is detected for a primary-key? I'm using a bottom-up approach for hibernate configuration (which means letting hibernate-tools generate the hibernate configuration using a jdbc-connection for you via reverse-engineering on an existing database schema). I've read this, but also this already (those two can be unrelated, but can also leave a hint). My hibernate.reveng.xml is the following: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-reverse-engineering SYSTEM "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" > <hibernate-reverse-engineering> <table name="ORDERS"> <primary-key> <!-- setting up a specific id generator for a table --> <generator class="sequence"> <param name="sequence">ORDERS_ORDER_ID_seq</param> </generator> <key-column name="ORDER_ID"/> </primary-key> </table> </hibernate-reverse-engineering> And I'm expecting it to generate an Orders.hbm.xml file like this: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2010-06-06 18:55:42 by Hibernate Tools 3.2.2.GA --> <hibernate-mapping> <class name="some.package.Orders" table="orders" schema="public"> <id name="orderId" type="long"> <column name="order_id" /> <generator class="sequence"> <param name="sequence">ORDERS_ORDER_ID_seq</param> </generator> </id> ... </class> </hibernate-mapping> ...but receiving this instead: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2010-06-06 18:55:42 by Hibernate Tools 3.2.2.GA --> <hibernate-mapping> <class name="some.package.Orders" table="orders" schema="public"> <id name="orderId" type="long"> <column name="order_id" /> <generator class="assigned" /> </id> ... </class> </hibernate-mapping> I know my hibernate.reveng.xml is being read by hibernate3-maven-plugin, as I experience maven errors whenever syntax errors appear in the file, so pom.xml seems to be correct and hibernate.reveng.xml syntactically correct. Any clues?

• Maven best practice for generating multiple jars with different/filtered classes ?

  - by jaguard

  I developed a Java utility library (similarly to Apache Commons) that I use in various projects. Additionally to fat clients I also use it for mobile clients (PDA with J9 Foundation profile). In time the library that started as a single project spread over multiple packages. As a result I end up with a lot of functionality but not really needed in all the projects. Since this library is also used inside some mobile/PDA projects I need a way to collect just the used classes and generate the actual specialized jars Currently in the projects that area using this library, I have Ant jar tasks that generate (from the utility project) the specialized jar files (ex: my-util-1.0-pda.jar, my-util-1.0-rcp.jar) using include/exclude jar task features. This is mostly needed due to the generated jar size constraints for the mobile projects. Migrating now to Maven I just wonder if there are any best practices to arrive to something similar so I consider the following scenarios: [1] - additionally to the main jar artifact (my-lib-1.0.jar) also generating inside my-lib project the separate/specialized artifacts using classifiers (ex: my-lib-1.0-pda.jar) using Maven Jar Plugin or Maven Assembly Plugin filtering/includes ... I'm not very comfortable with this approach since it pollute the library with library consumers demands (filters) [2] - Create additional Maven projects for all the specialized clients/projects, that will "wrap" the "my-lib" and generate the filtered jar artifacts (ex: my-lib-wrapper-pda-1.0 ...etc). As a result, these wrapper projects will include the filtering (to generate the filtered artifact) and will depend just on the "my-lib" project and the client projects will depend on my-lib-wrapper-xxx-1.0 instead of my-lib-1.0. This approach my look problematic since even that will let "my-lib" project intact (with no additional classifiers & artifacts), basically will double the number of projects since for every client project I'll have one just to collect the needed classes from the "my-util" library ("my-pda-app" project will need a "my-lib-wrapper-for-my-pda-app" project/dependency) [3] - Into the every client project that use the library (ex: my-pda-app) add some specialized Maven plugins to trim - out (when generating the final artifact/package) the un-needed classes (ex: maven-assembly-plugin, maven-jar-plugin, proguard-maven-plugin) What is the best practice for solving this kind of problems in the "Maven way" ?!

• Maven best practice for generating artifacts for multiple environments [prod, test, dev] with CI/Hud

  - by jaguard

  I have a project that need to be deployed into multiple environments (prod, test, dev). The main differences mainly consist in configuration properties/files. My idea was to use profiles and overlays to copy/configure the specialized output. But I'm stuck into if I have to generate multiple artifacts with specialized classifiers (ex: "my-app-1.0-prod.zip/jar", "my-app-1.0-dev.zip/jar") or should I create multiple projects, one project for every environment ?! Should I use maven-assembly-plugin to generate multiple artifacts for every environment ? Anyway, I'll need to generate all them at once so it seams that the profiles does not fit ... still puzzled :( Any hints/examples/links will be more than welcomed. As a side issue, I'm also wondering how to achieve this in a CI Hudson/Bamboo to generate and deploy these generated artifacts for all the environments, to their proper servers (ex: using SCP Hudson plugin) ?

• MySQL Syslog Audit Plugin

  - by jonathonc

  This post shows the construction process of the Syslog Audit plugin that was presented at MySQL Connect 2012. It is based on an environment that has the appropriate development tools enabled including gcc,g++ and cmake. It also assumes you have downloaded the MySQL source code (5.5.16 or higher) and have compiled and installed the system into the /usr/local/mysql directory ready for use.  The information provided below is designed to show the different components that make up a plugin, and specifically an audit type plugin, and how it comes together to be used within the MySQL service. The MySQL Reference Manual contains information regarding the plugin API and how it can be used, so please refer there for more detailed information. The code in this post is designed to give the simplest information necessary, so handling every return code, managing race conditions etc is not part of this example code. Let's start by looking at the most basic implementation of our plugin code as seen below: /*    Copyright (c) 2012, Oracle and/or its affiliates. All rights reserved.    Author:  Jonathon Coombes    Licence: GPL    Description: An auditing plugin that logs to syslog and                 can adjust the loglevel via the system variables. */ #include <stdio.h> #include <string.h> #include <mysql/plugin_audit.h> #include <syslog.h> There is a commented header detailing copyright/licencing and meta-data information and then the include headers. The two important include statements for our plugin are the syslog.h plugin, which gives us the structures for syslog, and the plugin_audit.h include which has details regarding the audit specific plugin api. Note that we do not need to include the general plugin header plugin.h, as this is done within the plugin_audit.h file already. To implement our plugin within the current implementation we need to add it into our source code and compile. > cd /usr/local/src/mysql-5.5.28/plugin > mkdir audit_syslog > cd audit_syslog A simple CMakeLists.txt file is created to manage the plugin compilation: MYSQL_ADD_PLUGIN(audit_syslog audit_syslog.cc MODULE_ONLY) Run the cmake  command at the top level of the source and then you can compile the plugin using the 'make' command. This results in a compiled audit_syslog.so library, but currently it is not much use to MySQL as there is no level of api defined to communicate with the MySQL service. Now we need to define the general plugin structure that enables MySQL to recognise the library as a plugin and be able to install/uninstall it and have it show up in the system. The structure is defined in the plugin.h file in the MySQL source code.  /*   Plugin library descriptor */ mysql_declare_plugin(audit_syslog) {   MYSQL_AUDIT_PLUGIN,           /* plugin type                    */   &audit_syslog_descriptor,     /* descriptor handle               */   "audit_syslog",               /* plugin name                     */   "Author Name",                /* author                          */   "Simple Syslog Audit",        /* description                     */   PLUGIN_LICENSE_GPL,           /* licence                         */   audit_syslog_init,            /* init function     */   audit_syslog_deinit,          /* deinit function */   0x0001,                       /* plugin version                  */   NULL,                         /* status variables        */   NULL,                         /* system variables                */   NULL,                         /* no reserves                     */   0,                            /* no flags                        */ } mysql_declare_plugin_end; The general plugin descriptor above is standard for all plugin types in MySQL. The plugin type is defined along with the init/deinit functions and interface methods into the system for sharing information, and various other metadata information. The descriptors have an internally recognised version number so that plugins can be matched against the api on the running server. The other details are usually related to the type-specific methods and structures to implement the plugin. Each plugin has a type-specific descriptor as well which details how the plugin is implemented for the specific purpose of that plugin type. /*   Plugin type-specific descriptor */ static struct st_mysql_audit audit_syslog_descriptor= {   MYSQL_AUDIT_INTERFACE_VERSION,                        /* interface version    */   NULL,                                                 /* release_thd function */   audit_syslog_notify,                                  /* notify function      */   { (unsigned long) MYSQL_AUDIT_GENERAL_CLASSMASK |                     MYSQL_AUDIT_CONNECTION_CLASSMASK }  /* class mask           */ }; In this particular case, the release_thd function has not been defined as it is not required. The important method for auditing is the notify function which is activated when an event occurs on the system. The notify function is designed to activate on an event and the implementation will determine how it is handled. For the audit_syslog plugin, the use of the syslog feature sends all events to the syslog for recording. The class mask allows us to determine what type of events are being seen by the notify function. There are currently two major types of event: 1. General Events: This includes general logging, errors, status and result type events. This is the main one for tracking the queries and operations on the database. 2. Connection Events: This group is based around user logins. It monitors connections and disconnections, but also if somebody changes user while connected. With most audit plugins, the principle behind the plugin is to track changes to the system over time and counters can be an important part of this process. The next step is to define and initialise the counters that are used to track the events in the service. There are 3 counters defined in total for our plugin - the # of general events, the # of connection events and the total number of events.  static volatile int total_number_of_calls; /* Count MYSQL_AUDIT_GENERAL_CLASS event instances */ static volatile int number_of_calls_general; /* Count MYSQL_AUDIT_CONNECTION_CLASS event instances */ static volatile int number_of_calls_connection; The init and deinit functions for the plugin are there to be called when the plugin is activated and when it is terminated. These offer the best option to initialise the counters for our plugin: /*  Initialize the plugin at server start or plugin installation. */ static int audit_syslog_init(void *arg __attribute__((unused))) {     openlog("mysql_audit:",LOG_PID|LOG_PERROR|LOG_CONS,LOG_USER);     total_number_of_calls= 0;     number_of_calls_general= 0;     number_of_calls_connection= 0;     return(0); } The init function does a call to openlog to initialise the syslog functionality. The parameters are the service to log under ("mysql_audit" in this case), the syslog flags and the facility for the logging. Then each of the counters are initialised to zero and a success is returned. If the init function is not defined, it will return success by default. /*  Terminate the plugin at server shutdown or plugin deinstallation. */ static int audit_syslog_deinit(void *arg __attribute__((unused))) {     closelog();     return(0); } The deinit function will simply close our syslog connection and return success. Note that the syslog functionality is part of the glibc libraries and does not require any external factors.  The function names are what we define in the general plugin structure, so these have to match otherwise there will be errors. The next step is to implement the event notifier function that was defined in the type specific descriptor (audit_syslog_descriptor) which is audit_syslog_notify. /* Event notifier function */ static void audit_syslog_notify(MYSQL_THD thd __attribute__((unused)), unsigned int event_class, const void *event) { total_number_of_calls++; if (event_class == MYSQL_AUDIT_GENERAL_CLASS) { const struct mysql_event_general *event_general= (const struct mysql_event_general *) event; number_of_calls_general++; syslog(audit_loglevel,"%lu: User: %s Command: %s Query: %s\n", event_general->general_thread_id, event_general->general_user, event_general->general_command, event_general->general_query ); } else if (event_class == MYSQL_AUDIT_CONNECTION_CLASS) { const struct mysql_event_connection *event_connection= (const struct mysql_event_connection *) event; number_of_calls_connection++; syslog(audit_loglevel,"%lu: User: %s@%s[%s] Event: %d Status: %d\n", event_connection->thread_id, event_connection->user, event_connection->host, event_connection->ip, event_connection->event_subclass, event_connection->status ); } }   In the case of an event, the notifier function is called. The first step is to increment the total number of events that have occurred in our database.The event argument is then cast into the appropriate event structure depending on the class type, of general event or connection event. The event type counters are incremented and details are sent via the syslog() function out to the system log. There are going to be different line formats and information returned since the general events have different data compared to the connection events, even though some of the details overlap, for example, user, thread id, host etc. On compiling the code now, there should be no errors and the resulting audit_syslog.so can be loaded into the server and ready to use. Log into the server and type: mysql> INSTALL PLUGIN audit_syslog SONAME 'audit_syslog.so'; This will install the plugin and will start updating the syslog immediately. Note that the audit plugin attaches to the immediate thread and cannot be uninstalled while that thread is active. This means that you cannot run the UNISTALL command until you log into a different connection (thread) on the server. Once the plugin is loaded, the system log will show output such as the following: Oct  8 15:33:21 machine mysql_audit:[8337]: 87: User: root[root] @ localhost []  Command: (null)  Query: INSTALL PLUGIN audit_syslog SONAME 'audit_syslog.so' Oct  8 15:33:21 machine mysql_audit:[8337]: 87: User: root[root] @ localhost []  Command: Query  Query: INSTALL PLUGIN audit_syslog SONAME 'audit_syslog.so' Oct  8 15:33:40 machine mysql_audit:[8337]: 87: User: root[root] @ localhost []  Command: (null)  Query: show tables Oct  8 15:33:40 machine mysql_audit:[8337]: 87: User: root[root] @ localhost []  Command: Query  Query: show tables Oct  8 15:33:43 machine mysql_audit:[8337]: 87: User: root[root] @ localhost []  Command: (null)  Query: select * from t1 Oct  8 15:33:43 machine mysql_audit:[8337]: 87: User: root[root] @ localhost []  Command: Query  Query: select * from t1 It appears that two of each event is being shown, but in actuality, these are two separate event types - the result event and the status event. This could be refined further by changing the audit_syslog_notify function to handle the different event sub-types in a different manner.  So far, it seems that the logging is working with events showing up in the syslog output. The issue now is that the counters created earlier to track the number of events by type are not accessible when the plugin is being run. Instead there needs to be a way to expose the plugin specific information to the service and vice versa. This could be done via the information_schema plugin api, but for something as simple as counters, the obvious choice is the system status variables. This is done using the standard structure and the declaration: /*  Plugin status variables for SHOW STATUS */ static struct st_mysql_show_var audit_syslog_status[]= {   { "Audit_syslog_total_calls",     (char *) &total_number_of_calls,     SHOW_INT },   { "Audit_syslog_general_events",     (char *) &number_of_calls_general,     SHOW_INT },   { "Audit_syslog_connection_events",     (char *) &number_of_calls_connection,     SHOW_INT },   { 0, 0, SHOW_INT } };   The structure is simply the name that will be displaying in the mysql service, the address of the associated variables, and the data type being used for the counter. It is finished with a blank structure to show that there are no more variables. Remember that status variables may have the same name for variables from other plugin, so it is considered appropriate to add the plugin name at the start of the status variable name to avoid confusion. Looking at the status variables in the mysql client shows something like the following: mysql> show global status like "audit%"; +--------------------------------+-------+ | Variable_name                  | Value | +--------------------------------+-------+ | Audit_syslog_connection_events | 1     | | Audit_syslog_general_events    | 2     | | Audit_syslog_total_calls       | 3     | +--------------------------------+-------+ 3 rows in set (0.00 sec) The final connectivity piece for the plugin is to allow the interactive change of the logging level between the plugin and the system. This requires the ability to send changes via the mysql service through to the plugin. This is done using the system variables interface and defining a single variable to keep track of the active logging level for the facility. /* Plugin system variables for SHOW VARIABLES */ static MYSQL_SYSVAR_STR(loglevel, audit_loglevel,                         PLUGIN_VAR_RQCMDARG,                         "User can specify the log level for auditing",                         audit_loglevel_check, audit_loglevel_update, "LOG_NOTICE"); static struct st_mysql_sys_var* audit_syslog_sysvars[] = {     MYSQL_SYSVAR(loglevel),     NULL }; So now the system variable 'loglevel' is defined for the plugin and associated to the global variable 'audit_loglevel'. The check or validation function is defined to make sure that no garbage values are attempted in the update of the variable. The update function is used to save the new value to the variable. Note that the audit_syslog_sysvars structure is defined in the general plugin descriptor to associate the link between the plugin and the system and how much they interact. Next comes the implementation of the validation function and the update function for the system variable. It is worth noting that if you have a simple numeric such as integers for the variable types, the validate function is often not required as MySQL will handle the automatic check and validation of simple types. /* longest valid value */ #define MAX_LOGLEVEL_SIZE 100 /* hold the valid values */ static const char *possible_modes[]= { "LOG_ERROR", "LOG_WARNING", "LOG_NOTICE", NULL };  static int audit_loglevel_check(     THD*                        thd,    /*!< in: thread handle */     struct st_mysql_sys_var*    var,    /*!< in: pointer to system                                         variable */     void*                       save,   /*!< out: immediate result                                         for update function */     struct st_mysql_value*      value)  /*!< in: incoming string */ {     char buff[MAX_LOGLEVEL_SIZE];     const char *str;     const char **found;     int length;     length= sizeof(buff);     if (!(str= value->val_str(value, buff, &length)))         return 1;     /*         We need to return a pointer to a locally allocated value in "save".         Here we pick to search for the supplied value in an global array of         constant strings and return a pointer to one of them.         The other possiblity is to use the thd_alloc() function to allocate         a thread local buffer instead of the global constants.     */     for (found= possible_modes; *found; found++)     {         if (!strcmp(*found, str))         {             *(const char**)save= *found;             return 0;         }     }     return 1; } The validation function is simply to take the value being passed in via the SET GLOBAL VARIABLE command and check if it is one of the pre-defined values allowed  in our possible_values array. If it is found to be valid, then the value is assigned to the save variable ready for passing through to the update function. static void audit_loglevel_update(     THD*                        thd,        /*!< in: thread handle */     struct st_mysql_sys_var*    var,        /*!< in: system variable                                             being altered */     void*                       var_ptr,    /*!< out: pointer to                                             dynamic variable */     const void*                 save)       /*!< in: pointer to                                             temporary storage */ {     /* assign the new value so that the server can read it */     *(char **) var_ptr= *(char **) save;     /* assign the new value to the internal variable */     audit_loglevel= *(char **) save; } Since all the validation has been done already, the update function is quite simple for this plugin. The first part is to update the system variable pointer so that the server can read the value. The second part is to update our own global plugin variable for tracking the value. Notice that the save variable is passed in as a void type to allow handling of various data types, so it must be cast to the appropriate data type when assigning it to the variables. Looking at how the latest changes affect the usage of the plugin and the interaction within the server shows: mysql> show global variables like "audit%"; +-----------------------+------------+ | Variable_name         | Value      | +-----------------------+------------+ | audit_syslog_loglevel | LOG_NOTICE | +-----------------------+------------+ 1 row in set (0.00 sec) mysql> set global audit_syslog_loglevel="LOG_ERROR"; Query OK, 0 rows affected (0.00 sec) mysql> show global status like "audit%"; +--------------------------------+-------+ | Variable_name                  | Value | +--------------------------------+-------+ | Audit_syslog_connection_events | 1     | | Audit_syslog_general_events    | 11    | | Audit_syslog_total_calls       | 12    | +--------------------------------+-------+ 3 rows in set (0.00 sec) mysql> show global variables like "audit%"; +-----------------------+-----------+ | Variable_name         | Value     | +-----------------------+-----------+ | audit_syslog_loglevel | LOG_ERROR | +-----------------------+-----------+ 1 row in set (0.00 sec)   So now we have a plugin that will audit the events on the system and log the details to the system log. It allows for interaction to see the number of different events within the server details and provides a mechanism to change the logging level interactively via the standard system methods of the SET command. A more complex auditing plugin may have more detailed code, but each of the above areas is what will be involved and simply expanded on to add more functionality. With the above skeleton code, it is now possible to create your own audit plugins to implement your own auditing requirements. If, however, you are not of the coding persuasion, then you could always consider the option of the MySQL Enterprise Audit plugin that is available to purchase.

• Using Maven to Deploy to Weblogic Clusters

  - by Mark Sailes

  org.codehaus.mojo weblogic-maven-plugin 2.9.1 We're currently using the weblogic maven plugin successfully to deploy to our local WebLogic 9.2 instances. When we try to deploy to a remote environment we have a problem. We use a two machine cluster, with the admin server and managed server on one machine, and another managed server on a seperate machine. When your plugin uploads the application to the admin server, it doesn't copy it to the second managed server on the seperate machine. This then causes the second managed server a problem, as it cannot find the application in the location where the admin server saved it on its own machine. Config below <configuration> <adminServerHostName>${weblogic.adminServerHostName}</adminServerHostName> <adminServerPort>${weblogic.adminServerPort}</adminServerPort> <adminServerProtocol>${weblogic.adminServerProtocol}</adminServerProtocol> <userId>${weblogic.userId}</userId> <password>${weblogic.password}</password> <upload>${weblogic.upload}</upload> <remote>${weblogic.remote}</remote> <verbose>${weblogic.verbose}</verbose> <debug>${weblogic.debug}</debug> <stage>${weblogic.stage}</stage> <targetNames>${weblogic.targetNames}</targetNames> <exploded>${weblogic.exploded}</exploded> </configuration> <profile> <id>localhost</id> <properties> <weblogic.adminServerHostName>localhost</weblogic.adminServerHostName> <weblogic.adminServerPort>7001</weblogic.adminServerPort> <weblogic.adminServerProtocol>t3</weblogic.adminServerProtocol> <weblogic.userId>weblogic</weblogic.userId> <weblogic.password>weblogic</weblogic.password> <weblogic.upload>false</weblogic.upload> <weblogic.remote>false</weblogic.remote> <weblogic.verbose>true</weblogic.verbose> <weblogic.debug>true</weblogic.debug> <weblogic.stage>false</weblogic.stage> <weblogic.targetNames>AdminServer</weblogic.targetNames> <weblogic.exploded>false</weblogic.exploded> </properties> </profile> <profile> <id>dev</id> <properties> <weblogic.adminServerHostName>******</weblogic.adminServerHostName> <weblogic.adminServerPort>9141</weblogic.adminServerPort> <weblogic.adminServerProtocol>t3</weblogic.adminServerProtocol> <weblogic.userId>******</weblogic.userId> <weblogic.password>******</weblogic.password> <weblogic.upload>true</weblogic.upload> <weblogic.remote>true</weblogic.remote> <weblogic.verbose>true</weblogic.verbose> <weblogic.debug>true</weblogic.debug> <weblogic.stage>true</weblogic.stage> <weblogic.targetNames>dev_cluster01</weblogic.targetNames> <weblogic.exploded>false</weblogic.exploded> </properties> </profile>

• maven and unit testing - combining maven surefire plugin AND testNG eclipse plugin

  - by lisak

  Hey, could you please share your way of unit testing in eclipse ? Are you using surefire plugin, m2eclipse & maven, or only testNG eclipse plugin ? Do you combine these alternatives ? I'm using testNG + maven surefire-plugin and I had been using the testNG eclipse plugin a year ago so that I could see the results in testNG view. Then I started using Maven, but when I do "maven test phase" using m2eclipse, there is only console output and surefire reports that I can check in browser and to choose what test suite, test, or test method can be set up only via testng.xml. On the other hand, if you use only surefire plugin and you have some specific settings regarding classpath etc., that you rely on, then running tests via testNG eclipse plugin doesn't have to be compatible with your code. Using surefire plugin, the classpath is different - target/test-classes and target/classes - than using testNG plugin, that is using the project classpath. How do you go about what I was just talking about? Is it possible to synchronize "maven test" using m2eclipse and surefire plugin WITH testNG eclipse plugin and view ? EDITED: I'm also wondering, why the Maven project ("Java build path") output folder is target/classes for src/main and src/test whereas surefire plugin makes two locations target/test-classes and target/classes Thank you very much for your your opinions.

• Maven plugin development [closed]

  - by Eugen Martynov

  Pre: I'm new with Maven. I used a lot of ant before. Qst: I decided to switch my project to maven since there are a lot of dependencies. But I have custom step in package phase (I'm BB dev - packing and signing) which is not available in maven yet. To process these tasks I have to download additional execs/jars. Is it common/have sense in Maven philosophy to load additional tools? Sure I could call ant from maven but it's not a question. Any helpful book about maven phases, philosophy and uses?

• Unable to import Maven project into IntelliJ IDEA

  - by del

  I'm having problems importing any Maven projects into IntelliJ IDEA. I create an empty Maven project like this: $ mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false Then I try to open the project in IDEA (File Open Project, then choose the pom.xml). A progress box saying "Reading pom.xml" displays for a few minutes, and then just disappears without opening the project. Looking in the IDEA log, I see some connection timeout exceptions like this: 2012-10-03 11:55:55,483 [ 16981] INFO - ution.rmi.RemoteProcessSupport - Port/ID: 18011/Maven2ServerImpl9407569f 2012-10-03 11:56:58,898 [ 80396] WARN - ution.rmi.RemoteProcessSupport - The cook failed to start due to java.net.ConnectException: Connection timed out 2012-10-03 11:57:55,483 [ 136981] WARN - ution.rmi.RemoteProcessSupport - java.rmi.NotBoundException: _DEAD_HAND_ 2012-10-03 11:57:55,484 [ 136982] WARN - ution.rmi.RemoteProcessSupport - at sun.rmi.registry.RegistryImpl.lookup(RegistryImpl.java:106) 2012-10-03 11:57:55,484 [ 136982] WARN - ution.rmi.RemoteProcessSupport - at com.intellij.execution.rmi.RemoteServer.start(RemoteServer.java:73) 2012-10-03 11:57:55,484 [ 136982] WARN - ution.rmi.RemoteProcessSupport - at org.jetbrains.idea.maven.server.RemoteMavenServer.main(RemoteMavenServer.java:22) 2012-10-03 11:58:01,749 [ 143247] ERROR - com.intellij.ide.IdeEventQueue - Error during dispatching of java.awt.event.MouseEvent[MOUSE_RELEASED,(65,116),absolute(64,140),button=1,modifiers=Button1,clickCount=1] on frame0 java.lang.RuntimeException: Cannot reconnect. at org.jetbrains.idea.maven.server.RemoteObjectWrapper.perform(RemoteObjectWrapper.java:82) at org.jetbrains.idea.maven.server.MavenServerManager.applyProfiles(MavenServerManager.java:311) at org.jetbrains.idea.maven.project.MavenProjectReader.applyProfiles(MavenProjectReader.java:369) at org.jetbrains.idea.maven.project.MavenProjectReader.doReadProjectModel(MavenProjectReader.java:98) at org.jetbrains.idea.maven.project.MavenProjectReader.readProject(MavenProjectReader.java:52) at org.jetbrains.idea.maven.project.MavenProject.read(MavenProject.java:405) at org.jetbrains.idea.maven.project.MavenProjectsTree.doUpdate(MavenProjectsTree.java:534) at org.jetbrains.idea.maven.project.MavenProjectsTree.doAdd(MavenProjectsTree.java:481) at org.jetbrains.idea.maven.project.MavenProjectsTree.update(MavenProjectsTree.java:442) at org.jetbrains.idea.maven.project.MavenProjectsTree.updateAll(MavenProjectsTree.java:413) at org.jetbrains.idea.maven.wizards.MavenProjectBuilder.readMavenProjectTree(MavenProjectBuilder.java:198) at org.jetbrains.idea.maven.wizards.MavenProjectBuilder.access$800(MavenProjectBuilder.java:44) at org.jetbrains.idea.maven.wizards.MavenProjectBuilder$3.run(MavenProjectBuilder.java:179) at org.jetbrains.idea.maven.utils.MavenUtil$8.run(MavenUtil.java:388) at com.intellij.openapi.progress.impl.ProgressManagerImpl$TaskRunnable.run(ProgressManagerImpl.java:469) at com.intellij.openapi.progress.impl.ProgressManagerImpl$6.run(ProgressManagerImpl.java:288) at com.intellij.openapi.progress.impl.ProgressManagerImpl$2.run(ProgressManagerImpl.java:178) at com.intellij.openapi.progress.impl.ProgressManagerImpl.executeProcessUnderProgress(ProgressManagerImpl.java:218) at com.intellij.openapi.progress.impl.ProgressManagerImpl.runProcess(ProgressManagerImpl.java:169) at com.intellij.openapi.application.impl.ApplicationImpl$8$1.run(ApplicationImpl.java:641) at com.intellij.openapi.application.impl.ApplicationImpl$6.run(ApplicationImpl.java:434) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) at com.intellij.openapi.application.impl.ApplicationImpl$1$1.run(ApplicationImpl.java:145) Caused by: java.rmi.RemoteException: Cannot start maven service;

• Where can I find useful Maven documentation?

  - by jprete

  I don't have to play with Maven configuation often, but when I do, it's usually to do something odd, like use a build plugin that hasn't matured enough to be on the main Maven repositories. The Maven documentation that I find doesn't cover unusual use cases well and tends to assume you already know what you're doing. Where can I find really useful, well-written documentation on Maven that also covers the corner cases of usage?

• Maven does not resolve a local Grails plug-in

  - by Drew

  My goal is to take a Grails web application and build it into a Web ARchive (WAR file) using Maven, and the key is that it must populate the "plugins" folder without live access to the internet. An "out of the box" Grails webapp will already have the plugins folder populated with JAR files, but the maven build script should take care of populating it, just like it does for any traditional WAR projects (such as WEB-INF/lib/ if it's empty) This is an error when executing mvn grails:run-app with Grails 1.1 using Maven 2.0.10 and org.grails:grails-maven-plugin:1.0. (This "hibernate-1.1" plugin is needed to do GORM.) [INFO] [grails:run-app] Running pre-compiled script Environment set to development Plugin [hibernate-1.1] not installed, resolving.. Reading remote plugin list ... Error reading remote plugin list [svn.codehaus.org], building locally... Unable to list plugins, please check you have a valid internet connection: svn.codehaus.org Reading remote plugin list ... Error reading remote plugin list [plugins.grails.org], building locally... Unable to list plugins, please check you have a valid internet connection: plugins.grails.org Plugin 'hibernate' was not found in repository. If it is not stored in a configured repository you will need to install it manually. Type 'grails list-plugins' to find out what plugins are available. The build machine does not have access to the internet and must use an internal/enterprise repository, so this error is just saying that maven can't find the required artifact anywhere. That dependency is already included with the stock Grails software that's installed locally, so I just need to figure out how to get my POM file to unpackage that ZIP file into my webapp's "plugins" folder. I've tried installing the plugin manually to my local repository and making it an explicit dependency in POM.xml, but it's still not being recognized. Maybe you can't pull down grails plugins like you would a standard maven reference? mvn install:install-file -DgroupId=org.grails -DartifactId=grails-hibernate -Dversion=1.1 -Dpackaging=zip -Dfile=%GRAILS_HOME%/plugins/grails-hibernate-1.1.zip I can manually setup the Grails webapp from the command-line, which creates that local ./plugins folder properly. This is a step in the right direction, so maybe the question is: how can I incorporate this goal into my POM? mvn grails:install-plugin -DpluginUrl=%GRAILS_HOME%/plugins/grails-hibernate-1.1.zip Here is a copy of my POM.xml file, which was generated using an archetype. <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.samples</groupId> <artifactId>sample-grails</artifactId> <packaging>war</packaging> <name>Sample Grails webapp</name> <properties> <sourceComplianceLevel>1.5</sourceComplianceLevel> </properties> <version>0.0.1-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.grails</groupId> <artifactId>grails-crud</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>org.grails</groupId> <artifactId>grails-gorm</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>opensymphony</groupId> <artifactId>oscache</artifactId> <version>2.4</version> <exclusions> <exclusion> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> </exclusion> <exclusion> <groupId>javax.jms</groupId> <artifactId>jms</artifactId> </exclusion> <exclusion> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>hsqldb</groupId> <artifactId>hsqldb</artifactId> <version>1.8.0.7</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.5.6</version> <scope>runtime</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- <dependency> <groupId>org.grails</groupId> <artifactId>grails-hibernate</artifactId> <version>1.1</version> <type>zip</type> </dependency> --> </dependencies> <build> <pluginManagement /> <plugins> <plugin> <groupId>org.grails</groupId> <artifactId>grails-maven-plugin</artifactId> <version>1.0</version> <extensions>true</extensions> <executions> <execution> <goals> <goal>init</goal> <goal>maven-clean</goal> <goal>validate</goal> <goal>config-directories</goal> <goal>maven-compile</goal> <goal>maven-test</goal> <goal>maven-war</goal> <goal>maven-functional-test</goal> </goals> </execution> </executions> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>${sourceComplianceLevel}</source> <target>${sourceComplianceLevel}</target> </configuration> </plugin> </plugins> </build> </project>

• Why 2 versions of jetty maven plugins ?

  - by Flueras Bogdan

  Hello, I set up a new webapp maven project and wanted to test it with jetty's maven plugin. So issuded in the console the command: mvn jetty:run After defining the pluginGroup in Maven's setting file I ran once again the command. Unfortunately, it failed because i was using one of the below mentioned versions of the plugin. The first has artifact id: maven-jetty-plugin and the 2nd:jetty-maven-plugin. Why there are 2 maven based plugins for achieving the same thing - running jetty? Why do they have to bring so much confusion? Or be so kind as to explain me the differences between them. Thank you.
