The problem was that it could not find any tsconfig files
[sonarlint-analysis-engine] INFO sonarlint - Found 0 tsconfig.json file(s): []
I could make it run by setting sonar.typescript.tsconfigPath to the absolut path. Any chance someone knows how the baseDir Path for sonarQube is set? Because mine is pointing to a wrong path and i couldn’t set it with sonar.projectBaseDir
