I am migrating an application from ant build to maven 3 build. This app is composed by :

• A parent project specifying all the modules to build
• A project generating classes with jaxb and building a jar with them
• A project building an ejb project
• 3 projects building war modules
• 1 project building an ear

Here is an extract from my parent pom :

<groupId>com.test</groupId>
<artifactId>P</artifactId>
<packaging>pom</packaging>
<version>04.01.00</version>

<modules>
    <module>../PValidationJaxb</module> <-- jar
    <module>../PValidation</module> <-- ejb
    <module>../PImport</module> <-- war
    <module>../PTerminal</module> <-- war
    <module>../PWebService</module> <-- war
    <module>../PEAR</module> <-- ear
</modules>

I have several problems which I think have the same origin, probably a dependency management issue that I cannot figure out :

• The generated modules are different depending on if I build from the parent pom or a single module. Typically if I build PImport only, the generated war is similar to what I had with my ant build and if I build from the parent pom, my war took 20MB, a lot of dependencies from other modules had been added. Both wars are running well.

• My project PWebService has unit tests to be executed during the build. It is using mock-ejb which has cglib as dependency. Having a problem of ClassNotFound with this one, I had to exclude it and add a dependency to cglib-nodep (see last pom extract). If I then build only this module, it is working well. But if I build from the parent project, it fails because other dependencies in other modules also had an implicit dependency on cglib. I had to exclude it in every modules pom and add the dependency to cglib-nodep everywhere to make it run.

Do I miss something important in my configuration ?

The PValidation pom extract :

It is creating a jar containing an ejb with interfaces generated by xdoclet, as well as a client jar.

The PImport pom extract :

It depends on both Jaxb generated jar and the ejb client jar.
