Just to chime in. I am not sure if deleting your .kepler directory is
the solution to your problem or not. But, if it is, the best way to do
it is by typing:
ant clean-cache
That command works across platforms and will delete your .kepler directory.
And no, deleting the .kepler directory will not cause Kepler to
"misbehave." (Although, sometimes the .kepler directory does mask some
problems that exist, and it may sometimes that deleting .kepler caused a
problem. But deleting .kepler doesn't cause such problems, it merely
unmasks them.)
