I have got a bad news. There appears to be a bug in all versions of
maven upto 2.0.8 which is why even my patch did not fix the problem.
Prior to maven 2.0.9, maven used to use a HashSet as opposed to any kind
of List to store dependencies, as a result the classpath used during
compilation can't be predicted. It has been fixed in 2.0.9. So, we
should probably switch to using 2.0.9 in trunk.
Try using maven 2.0.9 and let us know if the problem goes away.
Thanks,
Sahoo
