Hello!
I use an empty quality profile with checkstyle report path (external issues).
All issues from checkstyle xml report display correctly, but I can’t use it in a quality gate, because of them not used in diff with previous project state:
I’m guessing your Checkstyle issues have been backdated to before the start of your New Code period. What’s the issue date (shown in the top-right corner of the issue box)?
Also, why wouldn’t you use at least the Sonar way rules?
