Getting started with Pylint for Jython (jython2.5.1)

Question

We have a ton of Jython scripts for our deployment automation; I'd like Pylint to be part of our build pipeline.

I downloaded and installed logilab-astng, logilab-common and pylint from here: http://www.logilab.org/857

I installed the logilab libraries successfully using:

jython setup.py install

However, when I attempt to install pylint i get the following output:

C:\temp\pylint-0.22.0.tar.gz\pylint-0.22.0>jython setup.py install

Any ideas?

Answer 1

you should not try to compile the test files : some of them are broken on purpose (they are test inputs for pylint).
