I've searched google and reviewed answers on StackOverflow, but cannot seem to resolve this problem. I recently joined this project and added a few things to the POM. Being a relative neophyte with Maven, I am not grasping the issue and the response I have seen have not been clarifying. I suspect it is the addition of Groovy to the project. I want to use Groovy & Spock for testing (and, hopefully, eventually for prod as well).

I found my answer. I had to add a version to the maven-compiler-plugin. Answering my own question for anyone else that might be struggling with this. The clue was http://jira.codehaus.org/browse/MSITE-233
