I want to extract all the properties from my pom.xml into a properties-file. These are the common properties like dependency-versions, plugin-versions and directories. I'm using the properties-maven-plugin, but its not working as i want it to.

The essential part of my pom.xml:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>properties-maven-plugin</artifactId>
  <version>1.0-alpha-1</version>
  <executions>
    <execution>
      <phase>initialize</phase>
      <goals>
        <goal>read-project-properties</goal>
      </goals>
      <configuration>
       <files>
          <file>${basedir}/pom.properties</file>
        </files>
      </configuration>
    </execution>
  </executions>
</plugin>

Now when i run "mvn properties:read-project-properties" i get the following error:

[INFO] One or more required plugin parameters are invalid/missing for 'properties:read-project-properties'

[0] Inside the definition for plugin 'properties-maven-plugin' specify the following:

<configuration>
  ...
  <files>VALUE</files>
</configuration>.

The pom.properties-file is located in the same dir as the pom.xml. What can i do to let the properties-maven-plugin read my properties-file?
