Unable to see Junit cobertura coverage reports in SonarQube

SonarQube is reporting the following for my project.

Unit Tests Coverage 0.0%; Line Coverage 0.0%; Condition Coverage 0.0%

It is not able to find the reports which was created immediately before the Sonar scan. I am using Jenkins to launch the SonarQube scan. In fact in the console output I can see the unit tests being executed and the reports saved in the surefire directory.

Below are the relevant logs from the console output.

[INFO] --- maven-surefire-plugin:2.12:test (default-test) @ earn-promotional-domain ---
[INFO] Surefire report directory: /var/jenkins/workspace/earn/surefire-reports

[INFO] [13:50:20.807] Sensor SurefireSensor
[INFO] [13:50:20.807] parsing /var/jenkins/workspace/earn/surefire-reports
[ERROR] [13:50:20.808] Reports path not found or is not a directory: /var/jenkins/workspace/earn/surefire-reports
[INFO] [13:50:20.808] Sensor SurefireSensor (done) | time=1ms
[INFO] [13:50:20.808] Sensor CoberturaSensor
[INFO] [13:50:20.808] parsing /var/jenkins/workspace/earn/site/cobertura/coverage.xml

I am using SonarQube 5.1.2. Please let me know if any other information is needed that will help to figure out the problem.

As @Jeel said, you can use an alternative plugin. But if you necessarily must use the cobertura plugin, you can modify it a little bit.

If I understand correctly, the cobertura:check goal forks a current lifecycle, merges a plugin specific configuration (cobertura-maven-plugin-X.X.jar\META-INF\maven\lifecycle.xml) and executes a forked lifecycle to the test phase. After that "check" mojo is executed.

To make cobertura not to fork a lifecycle you can comment <executePhase> tag in a plugin descriptor (cobertura-maven-plugin-X.X.jar\META-INF\maven\plugin.xml) for the check goal. Additionaly, you have to copy the configuration from lifecycle.xml to your build configuration. For version 2.7 there is only surefire configuration:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>${surefire.version}</version>
  <configuration>
    <classesDirectory>${project.build.directory}/generated-classes/cobertura</classesDirectory>
    <testFailureIgnore>false</testFailureIgnore>
  </configuration>
</plugin>

(possibly extending a default lifecycle using components.xml would also work).

In the last step you have to add an execution for the "instrument" goal in the "process-class" phase because it doesn't have a default phase in a plugin descriptor.

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>cobertura-maven-plugin</artifactId>
  <version>${cobertura.version}</version>
  <executions>
    <execution>
      <id>instrument-classes</id>
      <phase>process-classes</phase>
      <goals>
        <goal>instrument</goal>
      </goals>
    </execution>
    <execution>
      <id>check-coverage</id>
      <goals>
        <goal>clean</goal>
        <goal>check</goal>
      </goals>
    </execution>
  </executions>
</plugin>

If you prefer to stick with Cobertura rather than moving to Jacoco, you can try this alternative to cobertura maven plugin:

https://github.com/QualInsight/qualinsight-mojo-cobertura

Here are some advantages this mojo provides:

  • it runs tests once (instead of twice with cobertura-maven-plugin)
  • it allows you to split coverage (UT / IT / Overall)
  • you get rid of the "obsolete" Cobertura plugin for SonarQube

The documentation on the project's page explains how to add converted reports to SonarQube.

You are better off with Jacoco than cobertura. Cobertura has lot of open bugs yet to be addressed.

Also Jacoco provides a aggregator plugin which will aggregate the coverage from all child modules and display a comprehensive coverage.

Jacoco also doesnt require any additional plugin for SonarQube.

Here's a good example of implementing Jacoco: http://www.petrikainulainen.net/programming/maven/creating-code-coverage-reports-for-unit-and-integration-tests-with-the-jacoco-maven-plugin/
