SonarQube not picking up Unit Test Coverage

Question

I am having issues with sonar picking up the jacoco analysis report. Jenkins however is able to pick up the report and display the results. My project is a maven build, built by Jenkins. The jacoco report is generated by maven (configured in the pom). Sonar is executed by using the Jenkins plugin.

This is what I see on SonarQube:

This is the report i can see of the project in jenkins.

The maven plugin config:

<plugin>     <groupId>org.jacoco</groupId>     <artifactId>jacoco-maven-plugin</artifactId>     <version>0.6.4.201312101107</version>     <executions>       <execution>         <id>default-prepare-agent</id>         <goals>             <goal>prepare-agent</goal>         </goals>       </execution>       <execution>         <id>default-report</id>         <phase>prepare-package</phase>         <goals>             <goal>report</goal>         </goals>       </execution>       <execution>           <id>default-check</id>           <goals>               <goal>check</goal>           </goals>       </execution>     </executions> </plugin> 

Jenkins Sonar Plugin config

Answer 1

You were missing a few important sonar properties, Here is a sample from one of my builds:

sonar.jdbc.dialect=mssql sonar.projectKey=projectname sonar.projectName=Project Name sonar.projectVersion=1.0 sonar.sources=src sonar.language=java sonar.binaries=build/classes sonar.tests=junit sonar.dynamicAnalysis=reuseReports sonar.junit.reportsPath=build/test-reports sonar.java.coveragePlugin=jacoco sonar.jacoco.reportPath=build/test-reports/jacoco.exec 

The error in Jenkins console output can be pretty useful for getting code coverage to work.

Project coverage is set to 0% since there is no directories with classes.
Indicates that you have not set the Sonar.Binaries property correctly

No information about coverage per test
Indicates you have not set the Sonar.Tests property properly

Coverage information was not collected. Perhaps you forget to include debug information into compiled classes? Indicates that the sonar.binaries property was set correctly, but those files were not compiled in debug mode, and they need to be
