We are using SonarQube 5.6 for a code base with a lot of legacy code.
We defined a quality gate which checks that new code should be covered by at least 75%. Unfortunately there are classes which are not testable at all and minor code changes (e.g. logging) shouldn't fail the quality gate.
So the idea was to "tag" those classes with an annotation to exclude them for the quality gate analysis.
I have had a look at the extension guide but I'm still uncertain where to start. What options do I have and which would be the best way to go?
