How do you setup a maven java project that can also make use of groovy?

I'm working on a large existing java proje开发者_C百科ct using maven to manage our builds / releases. I'm interested in using groovy to replace some of our Java classes where we can benefit from it's dynamic nature.

How do I go about doing this using maven?
