I was looking at why the maven builds are a bit slow and found out one of the culprit is modello which overwrites its generated files even if there are no changes: that cascades to recompiling the module, checking the style again, making a new archive and then recompiling the dependant modules aso... That was fixed a few months ago with https://github.com/codehaus-plexus/modello/pull/116 Would it be possible to release modello to be able to incorporate the fix and continue the work on optimization the build ?
I'm willing to help in any way if that can actually speed up things... Cheers, Guillaume
