SonarCube pluging not working.

[Neil Watson]

Greetings,

I'm having trouble getting the SonarCube plugin to work, and I'm rather new to Jenkins.  The error from the build job is:

11:26:32 [workspace] $ /var/lib/jenkins/tools/hudson.plugins.sonar.SonarRunnerInstallation/sonarqube-scanner-2.8/bin/sonar-runner -X -e -Dsonar.jdbc.url=jdbc:mysql://10.120.8.27:3306/sonar?autoReconnect=true&useUnicode=true&characterEncoding=utf8 ******** -Dsonar.host.url=http://10.120.8.27:9000/sonar/ ******** ******** -Dsonar.projectBaseDir=/var/lib/jenkins/jobs/set-rel-ver-myapp-access_controller/workspace

Why is the plugin running the deprecated sonar-runner and what does the exception mean?

If you google for “Unsupported major.minor version 52.0” you’ll find the answer to that – you have class files compiled with one Java version (probably some pre-compiled .jars you got from somewhere), but you are running under a different Java version ( the class files are probably Java 8, and you are trying to run using Java 6 or 7).

As far as the deprecated issue is concerned, I can’t comment, sorry.

Matthew

Correct. Adding a JDK to Jenkins and specifying to use it in the SonarQube section of the job worked.
