SonarQube 7.9.1 LTS GitHub Enterprise 2.20.5 Jenkins 2.222.1 LTS I am using SonarQube PR decoration with GitHub Enterprise. Have noticed that the PR analysis brings some old issues (already reported on base branch) and reports them as ‘New’. What is the reason ? Scenario: Changed a file in PR …

Hi, Not having an author for the issues in the P/R makes me thing maybe the scanner failed to detect SCM information. Could you open the file in SonarQube and see if there is blame information (click on the bar at the left of the line to see it). Do you have the logs of the scanner for that pull re…

Hi @dmeneses , As I mentioned earlier there was no problem with SCM detection. Files which were changed were correctly detected and blame information was available.

So the line where the issue is located has an older blame date in the pull request compared to the same line in master? Could you share the logs of the scanner for the pull request analysis with debug enabled?
