I’m sold, am gonna set it up at home and plug it in to my Ant (ooh, Ant 1.6 is out!) build script.
Vim’s quickfix feature can take me right to the offending line where I can edit/delete as appropriate.
It’ll be invaluable in detecting unused import statements, incorrect javadoc etc.
Once I’m over the initial pain of getting my code into shape I think making it part of the edit/compile /run cycle will make my life easier in the long run.
