Kids these days have it easy:

$ pip install java2python

We need the ANTLR Python runtime before we can install java2python:

$ wget http://www.antlr.org/download/antlr-3.1.3.tar.gz

$ tar xfz antlr-3.1.3.tar.gz

$ cd antlr-3.1.3/runtime/Python/

$ python setup.py install

Now the goodness:

$ wget https://github.com/downloads/natural/java2python/java2python-0.5.tar.gz

$ tar xfz java2python-0.5.tar.gz

$ cd java2python

$ python setup.py install

The runtime dependency for java2python is the [Python runtime][] for [ANTLR][].

The exact version number is very important: java2python requires

[version 3.1.3 of the Python runtime][].

The development dependencies (what you need if you're coding java2python) are

[ANTLR][], also version 3.1.3, GNU make, and a JVM.
