It seems that Groovy project is inactive. There are no releases since year 2000.
I've found some more interesting (and active) GP environments like: ECJ (java based) or GPE (mono platform). There is also JAGA, it's dead now, but there is a chance for a second life (look at JAGA forum at sourceforge.net).
