Sonarlint is not connected to sonarqube 10

Sorry, for Eclipse sonar lint purpose we are using java 11

Yes i did around 7 to 8 times the below process

Issues: SonarLint is not connecting to the SonarQube in Eclipse via binding

Solution :

It seems that SonarLint local issue cache somehow got corrupted. You can fix the issue by manually deleting the cache. It is in <your workspace root>/.metadata/.plugins/org.eclipse.core.resources/.projects/<your eclipse project name>/org.sonarlint.eclipse.core/issues/
You can simply remove the entire folder, and the error should go away.
The consequence is that you’ll lose the “history” of your issues (when was the issue first discovered), so in the UI, all issues will have a fresh date

  1. Cleaning Eclipse workspace .eclipse .sonarlint

  2. Deleting earlier connections in the binding of SonarQube from eclipse

  3. Creating new connections in Eclipse for binding with sonarqube
