On the surface it looks simple: just add the dependency and you can run the example code.
However what the jython artifact doesn’t get you are the standard
python libraries like re. This means that as soon as you try to do
something like the code below, it will error out:
PythonInterpreter interp = new PythonInterpreter();
try {
interp.exec("import re");
}
catch (PyException ex) {
ex.printStackTrace();
}
The solution? Use the jython-standalone artifact which includes the
standard libraries. An other advantage is that it has the latest release
(2.5.2) while jython lags two minor revisions behind (2.5.0) in Maven
Central. A possible downside is the larger size of the jar.
