I googled for a solution and after a while /ant clean/ apparently worked for me.
Good, I am glad to hear it.
I regularly clean up my Subversion sandboxes by doing:
svn revert -R .
ant clobber cleanjars
ant clobber is like ant clean, but it cleans up even more things. And there
is also a cleanjars, which does not get run by 'ant clobber'.
For a really, really clean tree, you can do:
ant clobber cleanjars cleandocs junit-clean
:)
It takes a little while to get comfortable with the Derby build.xml
configuration, because it is pretty complicated. But after a little
bit of practice you'll feel more clear about what it is doing.
