- Fix: Sputnik suppresses error from PMD when the rules in configuration were not present in jar
- Change one error to more descriptive for user
OK. However it would be helpful if Sputnik can handle problem with configuration. Currently it shows only message on console so if you use invalid or missing pmd rule (It happened to me) so Sputnik did not inform me even PMD exited properly with proper message. Sputnik ignores such errors and kept going!.
