...
For now, just a rough list:
- Java 6 JDK
- either Maven 2.2.1 or Maven 3.0.0 -beta-3 or later (and point m2eclipse towards)
Both versions of Maven seem to work ok; probably makes sense to go with M3.0.0 now that it's out.
- Eclipse 3.6 Java edition
- subclipse for Subversion
- m2eclipse for maven
- findbugs
- emma
- groovy-eclipse (http://dist.springsource.org/release/GRECLIPSE/e3.6/)
