  • SonarQube: 8.2.0.32929
  • sonar-scanner: 3.0.3.778
  • jacoco: 0.8.4
  • jdk: 1.8
  • mvn: 3.6.3

What are you trying to achieve

I am trying to achieve code coverage by using sonar-scanner but I am getting code coverage 0 in sonarqube dashboard.

What have you tried so far to achieve this

I configured the multi-module java project using https://github.com/SonarSource/sonar-scanning-examples/tree/master/sonarqube-scanner-maven/maven-multimodule

and created sonar-project.properties file in base directory with below configuration

sonar.projectKey=org.sonarqube.sonarscanner-maven-aggregate
sonar.projectName=Sonar Scanner Maven Aggregate
sonar.projectVersion=1.0
sonar.language=java
sonar.java.binaries=.

If I use mvn sonar:sonar it works. but with sonar-scanner it is not working.

It works fine with sonarqube 7.8.

Any insight would be appreciated.

  • I don't know if this is related. I had to do some configuration of the jacoco plugin in the pom.xml, with the prepare-agent goal, and I think I was seeing 0 code coverage before that, but that was over a year ago, jacoco 0.8.2, and it wasn't a multi-module project. – David Conrad Apr 23 '20 at 19:04
  • I am facing it for multi module project. For single module it works fine. – saurabh landge Apr 23 '20 at 19:40

I fixed this issue.

while running sonar-scanner command, I added the xmlReportPaths as a define property like sonar-scanner -Dsonar.coverage.jacoco.xmlReportPaths=tests/target/site/jacoco-aggregate/jacoco.xml,../tests/target/site/jacoco-aggregate/jacoco.xml

If your projects are set up as multi-module, you will have to feed the coverage report from each module to the last module that will run as part of the build (probably integration tests modules)

Following the steps mentioned in this example project by Sonar team helped me https://github.com/SonarSource/sonar-scanning-examples/tree/master/sonarqube-scanner-maven/maven-multimodule

As you already followed these steps, one thing I was missing was the aggregated report was not generated in the last module and I was doing it in one module before that which was our integration test module. But there was one more deployment module in our case

  • It is able to aggregate all reports from all modules into 1 module. mvn sonar:sonar goal shows coverage as well. But I want to do it with sonar-scanner which is not working. – saurabh landge Apr 24 '20 at 07:15
