MSbuild Scanner warnings on "(SonarQube)Won't-fix" issues

Hi there,

we use:

  • Sonar Qube Developer Edition
  • Jenkins 2.182
  • SonarQube Scanner for Jenkins 2.9
  • SonarScanner for MSBuild 4.3.1

The problem:
We have marked some SonarQube issues as “Won’t fix” via the SonarQube platform, but the build via MSBuild still report the SQ-warnings.
The result of that is that the jenkins build is marked as unstable, which is correct and a desired behavior.
On the other hand SonarQube Overview is correct and shows zero issues.

But why do the build via MSBuild still report the warnings?
Is it possible that the “Won’t fix” issues won’t show up while the build?

Thank you in advance
