I think so.

If I forget the hierarchy store for now and put my files together with a
checkout of the fresnel/ directory, minus any files that rely on
Jena/Sesame2, I see only one repeated compilation error.
in Eclipse tells me the recover method is missing, so I added this based
on some quick Google searches:

protected void recover(RecognitionException ex, BitSet bs) throws
TokenStreamException {

I don't really know what that method is for, but the error goes away.

I'll try to put together a build system for generating a jar today.
