   Like the http://ant.apache.org/manual/Tasks/javac.html[javac ant task],
   the maven-compiler-plugin does not actually compile, but rather
  
positive.code: changes to the default lifecycle. The downside is, of course, that you
  need 31 lines of configuration to do this!

  == Sample project and source code
  
  There is an archetype available for this project. You can use it through
  a command like this:
  
  [source,xml]
  ------------------------------------------------------------------------------------
  mvn archetype:generate \
      -DarchetypeGroupId=org.codehaus.groovy \
      -DarchetypeArtifactId=groovy-eclipse-quickstart \
      -DarchetypeVersion=2.5.2-01 \
      -DgroupId=foo \
      -DartifactId=bar \
      -Dversion=1 \
      -DinteractiveMode=false \

  A
  https://svn.codehaus.org/groovy/eclipse/trunk/extras/groovy-eclipse-maven-tests[sample
  project] using the compiler plugin as well as the source code for the
  plugin itself are available from the
  https://github.com/groovy/groovy-eclipse/[github repository]:
  
  The full URL to the maven projects
  is:https://github.com/groovy/groovy-eclipse/tree/master/extrasThere are
  several projects in the repository:groovy-eclipse-compiler : the
  compiler plugin itself (an m2eclipse
  project).groovy-eclipse-batch-builder : a set of ant scripts and
  configuration files used to build the groovy-eclipse-batch artifact.
  This artifact is an amalgamation of all jars required for compiling
  Groovy and Java code in Eclipse, including ecj (the Eclipse compiler for
  Java), the non-UI components of Groovy-Eclipse, the Groovy jars, and
  various required Eclipse bundles.groovy-eclipse-maven-tests : a sample
  project that uses the compiler plugin (an m2eclipse
  project).org.codehaus.groovy.m2eclipse : an Eclipse plugin that provides
  integration between Groovy-Eclipse and m2eclipse (the Maven tooling for
  Eclipse).Feature org.codehaus.groovy.m2eclipse : an Eclipse feature that
  is required for building and releasing the org.codehaus.groovy.m2eclipse
  plugin.
  
  The sample project and archetype is not maintained as well as we would
  like. Some community help with this would be greatly appreciated. Please
  see http://jira.codehaus.org/browse/GRECLIPSE-1285[GRECLIPSE-1285].
