IT's a "bug"" that has already been fixed in SVN. However, you probably
don't want war:war on it's own (which won't do anything bug assemble a
war from the target files, if present) - you probably want "package"
(which compiles and tests, etc), which will not have this problem.

can it be that the path:

is the cause?
