If you are working with a team I suggest you check out our new support (only works in the plugin released yesterday) for XML resource files:
http://www.codenameone.com/3/post/2013/08/teamwork-and-other-things.htmlGenerally we keep all files under revision (although we use SVN and NetBeans).
We ignore:
build, dist (bin for eclipse guys) and nbproject/private
Everything else goes into SVN including the jars although that is something we sometimes choose not to add (it has downsides).
