I use the commercial version of Jalopy for my Java projects but it doesn't work on Groovy files. IntelliJ has a serviceable formatter but I don't like requiring a particular IDE.

              I've found that BUSL works really well on Groovy files. It's standalone too, so you can use it from your text editor or whatever.

              I accepted your answer since no others are forthcoming.  Thanks for letting me know about BUSL, I had never heard of it before.  I'm still in Jalopy withdrawal though ... It had lots of knobs for customization and I tweaked them all.

            the latest eclipse plugin will do some formatting and refactoring: http://groovy.codehaus.org/Eclipse+Plugin+Refactoring
