Description

Take this example snippet:

<plugin>
  <artifactId>maven-plugin-plugin</artifactId>
  <version>2.5</version>
  <executions>
    <execution>
      <phase>initialize</phase>
      <goals>
        <!-- NOTE: Both of these goals have an "outputDirectory" parameter but with different default values -->
        <goal>helpmojo</goal>
        <goal>descriptor</goal>
      </goals>
    </execution>
  </executions>
</plugin>

When running this with trunk, both mojos get configured with the same value for their outputDirectory parameter, i.e. the default value for one mojo pollutes the configuration of the other mojo such that one ends up with

target/generated-sources/plugin/HelpMojo.java
target/generated-sources/plugin/plugin.xml      <- this should have been generated in target/classes/META-INF/maven
