SonarQube Jacoco offline instrumentation shows 0% coverage in Maven Multi Module Project

Question

I am using Jacoco offline instrumentation as I have used PowerMockito for my test cases. Mine is Maven Multi Module Project. I am using PowerMockito 1.65 My SonarQube version is 6.7

JaCoCo generates HTML files in every module, But in SonarQube it is showing 0%

My parent pom.xml

<properties>
    <sonar.version>6.7</sonar.version>
    <sonar-java.version>4.2</sonar-java.version>
    <sonar.core.codeCoveragePlugin>jacoco</sonar.core.codeCoveragePlugin>
</properties>

JaCoCo Report

SonarQube Report

If you change the default file location for the coverage file which for the maven jacoco plugin is:

${project.build.directory}/jacoco.exec

You also need to tell the sonar plugin where to find it. Sonar uses a lot of properties for the plugin, the jacoco report file should be: sonar.jacoco.reportPaths Once the sonar plugin looks into the correct location it should work. Note to calculate the coverage sonar uses both the coverage files and the compiled classes.

Just a side note: you execute mvn clean install test sonar:sonar which is a bit redundant, since test is a phase before install an install would do the same. See Maven Life-Cycle. But that should not matter here.
