Groovy works extremely well with Intellij Idea. I often mix Java and Groovy in projects and for the most part it's seamless. I'll start something in Java and as soon as I run into something that should be done with a closure or functional idioms that would require 100 lines of java instead of 2 lines of groovy, I just change the file extension from .java to .groovy, write it as it should be and move on.
