I recently had to switch a Groovy 2 project from an Ant build to a Maven 2 build. This involved a fair amount of searching and trail and error so I thought I'd post the basic pom.xml that got the job done.

I elected to use the groovy-eclipse plugin instead of the alternatives described in the Compiling Groovy documentation. I also chose the "Do Nothing" option of putting the .groovy files under src/main/java because they were already mostly there in the existing project. This went fairly smoothly once I got past some problems with the plugin versions. Note that I included the pluginRepository for the compiler plugin in my pom.xml. I did that for getting this up and running, but I'll eventually move it to settings.xml.

Here's the pom.xml...
