[FIXED] SonarRunner can't find sonar.projectKey, sonar.projectName, sonar.projectVersion, sonar.sources

Issue

I am attempting to get Jenkins to run Sonar as a post-build step.

Jenkins runs SonarRunner [1] but this fails with:

ERROR: Error during Sonar runner execution
ERROR: Unable to execute Sonar
ERROR: Caused by: You must define the following mandatory properties for 'Unknown': sonar.projectKey, sonar.projectName, sonar.projectVersion, sonar.sources

If I run mvn sonar:sonar [2] instead it works fine. It almost sounds like SonarRunner is ignoring pom.xml. How do I get SonarRunner to pick up these properties from Maven?

Solution

UPDATE: Per https://docs.sonarqube.org/latest/analysis/scan/sonarscanner-for-jenkins/ the desired functionality is now available.

What a nice way to waste an evening...

According to this Sonar Runner is not meant for Maven projects. It turns out you're supposed to look under "Post-Build Actions" (not "Post-Build Steps") and you will find "Sonar". See here for more information.
