Question

I want to use the cpplint.py script to get coding style errors on the code. I managed to execute the python script in Jenkins and it posts the output to the console log. I want to parse the console log via the warnings plugin using the cpplint browser. Unfortunately, I get the following exception:

ERROR: Publisher hudson.plugins.warnings.WarningsPublisher aborted due to exception
java.lang.NullPointerException

This is curious, as I don’t provide any file to parse but have configured the plugin to parse the console log. Do I have to configure cpplint to produce a special output? Or is it just an error in the plugin? If you do need any further information, please ask.

Thanks for your help!

This was actually a bug in the plugin. Will be fixed in the next update of the warnings plugin.
