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.
