PMD and Checkstyle exclusions in pom.xml make a the build pass, but still cause checks to run and produces incorrect output.

Observed this today when introducing Qulice into a legacy project.

Environment:

• Medium size legacy project
• ~4.3k PMD violations in ~300 files ( yes really :) )
  • => PMD takes a lot of time to run (2-3 min), right now only excluding it fully on all files makes sense for irrelevant reasons

Issue Observed:

• When putting <exclude>pmd:.*</exclude> the build passes which is correct, but:
  • The output is [INFO] No PMD violations found in 3xx files, this is not correct
  • It appears PMD is still run on those files given that the build is not sped up and the PMD step still takes 2-3 minutes

What I would like to see here :):

• The output should be more like [INFO] No PMD violations found in 0 files, or obviously even better no PMD output at all.
• PMD should not be run if all files are excluded to speed up the build in cases like the above described.
• Please also make sure that the same behaviour is implemented for Checkstyle, it too should only run on files not excluded!
