Re: Import error with maven

python.home is a very important setting for Jython, since it is used to set
sys.prefix and sys.exec_prefix and corresponding paths. However, it usually
can be inferred by PySystemState#findRoot, but this inference was broken
for a python.home that was set to an empty string, and was just fixed in a
commit today: https://hg.python.org/jython/rev/b0d8aed3a8cd

The other change this commit introduced is that any ImportError that is
raised during the import of the site module now provides in its message
some additional diagnostic information, including how sys.path is being set.

If you can build Jython 2.7 (
https://wiki.python.org/jython/JythonDeveloperGuide), please take a look
and see how this changeset works for you. We should also have a release
candidate ready very soon.
