After upgrading project to openJDK 10 we are getting this error in Jenkins build. We tried to run it locally with the same version of SonarQube(6.7.5) and SonarJava plugin(5.7) where it worked fine. We didn't have any issues when running it with openJDK 8.
Jenkins console output:
Task :sonarqube FAILED
Task ':sonarqube' is not up-to-date because:
Task has not declared any outputs despite executing actions.
User cache: /home/jenkins/.sonar/cache
SonarQube server [http://localhost:9000] can not be reached
:sonarqube (Thread[Task worker for ':' Thread 69,5,main]) completed. Took 0.141 secs.
FAILURE: Build failed with an exception.
SonarQube doesn't support running on Java 10 yet. You will have to stay at Java 8 for the time being. Note that you can run the analysis sonar-scanner or mvn sonar:sonar on Java 10 without issues. Only the server will not run.
Update: Latest 7.9 LTS version of SonarQube supports running on Java 11
