Comment 2 Milos Kleint 2008-08-15 10:04:13 UTC 
not sure how this is maven related. it looks like an issue in module system.
Comment 3 Jesse Glick 2008-08-19 00:44:59 UTC 
From the logs, it looks like the DuplicateException is just a side-effect of the root problem, an ISE checking whether
an eager module can be enabled - which in turn seems likely to be caused by newly installed modules being created in
arbitrary order. Not sure if fix addresses the problem since there are no apparent steps to reproduce it. core-main

Log: Enabling available eager modules whenever any new module is created.
Looks like it will fix #144005, though it is not clear how that can be reproduced.
Comment 5 Jesse Glick 2008-08-19 22:48:20 UTC 
Found a simple way to reproduce (and confirm that fix works):

1. ant -Dcluster.config=basic clean build-nozip tryme

2. Tools > Plugin Manager

3. Under Available, select Java Profiler and Install.
Comment 6 Jesse Glick 2008-08-19 23:48:59 UTC 
Trying a different fix - just deleting code to enable eager modules as they are created. It seems this is not really
necessary anyway, since most client code which would create new modules will also try to enable some of them, which will
have the effect of enabling any available eager modules in batch mode, with much less overhead. core-main #8c44699b4277
