I recently discovered that if a parent pom adds an antrun plugin execution to build, that children can not add dependencies, which causes some problems further down in the build. I was going to use antrun to install LICENSE.txt and NOTICE.txt into target/classes/META- INF as a work around to the problem that occurs when we added them to build/resources that caused the maven-eclipse-plugin to barf.

So I finally gave up and create a new plugin which allows Groovy scripts to be executed inline and with the AntBuilder we can execute Ant bits, as well as perform logic operations all within a pom. And I setup the project-config pom to add an execution that will copy LICENSE.txt and NOTICE.txt from the module root to target/classes/ META-INF for all modules unless the packaging is pom, with:

    <plugin>
        <groupId>org.apache.geronimo.genesis.plugins</groupId>
        <artifactId>script-maven-plugin</artifactId>
        <version>1.0.0-SNAPSHOT</version>
        <executions>
            <execution>
                <id>install-licenses-and-notice</id>
                <phase>generate-resources</phase>
                <goals>
                    <goal>groovy</goal>
                </goals>
                <configuration>
                    <code>
                        if (project.packaging != "pom") {
                            def ant = new AntBuilder()

def dir = "${project.basedir}/target/ classes/META-INF"
                            ant.mkdir(dir: dir)
                            ant.copy(todir: dir) {
                                fileset(dir: "${project.basedir}") {
                                    include(name: "LICENSE.txt")
                                    include(name: "NOTICE.txt")
                                }
                            }
                        }
                    </code>
                </configuration>
            </execution>
        </executions>
    </plugin>

The new script-maven-plugin is a tad different than the groovy-maven- plugin in the mojo sandbox, primarily allows the code for the script to be defined in the pom or at an external URL. Also allows extra dependencies to be added outside of the normal Maven plugin dependency mechanism, since antrun has shown that it is broken for parent and child configurations.

There are still however a few issues remaining that prevent `mvn eclipse:eclipse` from generating clean .classpath files, which will be fixed when we move modules to use the standard m2 layout.
