SonarRunner can't find sonar.projectKey, sonar

Question

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?

Answer 1

There is some Maven GAV info data mapped into Jenkins variables, look at this thread: Automatically derive mandatory SonarQube properties from pom file in Jenkins

Answer 2

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.

Method 1: If you installed a scanner in Jenkins then just add the following in this location on your job
Post Steps -> Execute SonarQube Scanner -> Analysis properties

sonar.projectKey=myProject1
sonar.sources=.

Method 2: Another alternative is using the deprecated method which still works fine Post-build Actions -> SonarQube analysis with Maven

Method 3: Build -> Goals and options -> "enter the below script" -Dmaven.test.skip=true install sonar:sonar -Dsonar.forceAnalysis=true -Dsonar.host.url=http://localhost:9000/ -Dsonar.branch=my-branch-1
