Hi could you provide the full stacktrace and a bit more context : this is analyzed on sonarcloud ? (if not please specify version of SonarJava). Can you confirm that you compiled the project and provide the binaries to the analysis through sonar.java.binaries (this is done for you with a maven or gradle scanner).
Thanks
