      Description

      I upgraded my version of the Checkstyle plugin from 3.32 to 3.34 and started getting NullPointerExceptions when building the Apache Shindig project.

      The exception is coming from code that was introduced by this changeset: https://github.com/jenkinsci/checkstyle-plugin/commit/e79892bdb3873059ab04ad1e0569311262353f4c

      My guess is that "mojo.getConfigurationValue("outputFile", String.class)" is null or empty. I'm not sure what that should be returning or how it gets set in the environment. Have I missed some newly required configuration?

      Here's the NPE:
      mavenExecutionResult exceptions not empty
