sonarQube fails to generate coverage file - sonarqube

Question

Im having trouble getting sonarQube to output the coverage report of my java Spring project. Because of this it always displays 0.0% coverage in the interface. I followed this and it still will not generate the file. The following is the relevant part of the pom.xml and at the bottom is the log. By default the coverage report is supposed to be in target/site/jacoco/jacoco.xml; however even when I comment out <sonar.converage.jacoco.xmlReportPath/> it still does not output anything.
<sonar.coverage.jacoco.xmlReportPaths>${project.build.directory}/site/jacoco-aggregate/jacoco.xml
</sonar.coverage.jacoco.xmlReportPaths>
<sonar.exclusions>
**/atlas/base/api/config/*.java,
**/atlas/base/api/model/*.java,
**/atlas/base/api/repository/*.java
**/atlas/bse/api/ClientIntegrationApplication.java
</sonar.exclusions>

Answer 1

It seems that you're executing "mvn sonar:sonar" - the "sonar" goal will NOT generate the coverage report, it expects that the coverage report has already been generated. The "prepare-agent" goal is responsible for generating an .exec file and the "report" goal generates a .xml report from the .exec file.
In your configuration the "report" goal is bound to the package phase, did you run "mvn package" or "mvn install" before running "mvn sonar:sonar"?

Answer 2

My first guess is that your plugin is not set well. Here is a working example:
<!-- Dependencies needed for creating SonarQube coverage reports -->
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.8.7</version>
<executions>
<execution>
<id>prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>report</id>
<phase>prepare-package</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
<execution>
<id>post-unit-test</id>
<phase>test</phase>
<goals>
<goal>report</goal>
</goals>
<configuration>
<!-- Sets the path to the file which contains the execution data. -->
<dataFile>target/jacoco.exec</dataFile>
<!-- Sets the output directory for the code coverage report. -->
<outputDirectory>target/jacoco-ut</outputDirectory>
</configuration>
</execution>
</executions>
<configuration>
<systemPropertyVariables>
<jacoco-agent.destfile>target/jacoco.exec</jacoco-agent.destfile>
</systemPropertyVariables>
</configuration>
</plugin>
Please notice <id>post-unit-test</id> execution step and dataFile and outputDirectory elements. Here you should set paths.

Answer 3

The property is called sonar.coverage.jacoco.xmlReportPaths (note the "s"). Your text and your code sample specify different property names and values for this. Figure out where it is and use that. Different build configurations might put it in a different place. Look in the workspace of your build to see where the file was created.
