Compiling Jython From Source generate org.python.parser directory

Hello I am trying to compile the Jython Java Source Code from subversion. But it fails because there is no parser directory it should be org.python.parser in org/python/parser. I read that this folder you need to generate. Any ideas how would be gr开发者_运维百科eat!

I found this link but its very dated and doesn't seem to explain anything at all

The Jython Developer Guide is what you need. You should just able to run ant in the top-level directory to compile it.
