Using Jython from Maven
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.
<dependency> <groupId>org.python</groupId> <artifactId>jython-standalone</artifactId> <version>2.5.2</version> </dependency> |
