**Affects:** 3.6.0

Start by locating the Maven Checkstyle plugin's handling of the skip-property and the path that produces its execution output. Compare the skipped Checkstyle output with the examples in the issue, then add coverage for the expected informational message if the repository has a relevant test area. Done means a skipped execution clearly reports that it was skipped.
