Sonarqube coverage for multimodule projects with integration tests

[Arun_Kumar]

Sonarqube LTS version 9.9. Sonarqube deployed on a VM

I have a project with 3 modules: module 1, module 2, module 3. I’m using the maven plugin. So there is a pom.xml at the root level and one pom.xml each in the modules. Module 2 is completely integration tests. Module 1 pom’s parent pom is the spring framework one. So i created an aggregate project whose pom aggregates the report from the individual modules. something like the one below.
I get coverage for modules 1 and 3 but not for module 2 which is the integration tests module. Do i have to do anything different to get integration tests coverage?

<build>
    <plugins>
      
      <plugin>
         <groupId>org.jacoco</groupId>
         <artifactId>jacoco-maven-plugin</artifactId>
         <version>${jacoco-maven-plugin.version}</version>
         <executions>
            <execution>
              <id>${project.artifactId}-prepare-agent</id>
              <goals>
                <goal>prepare-agent</goal>
              </goals>

            <execution>

                </dataFileIncludes>
                <outputDirectory>${project.reporting.outputDirectory}/jacoco-aggregate</outputDirectory>

Hey there.

Have you seen the multi-module section of this guide?

[Coverage & Test Data] Importing JaCoCo coverage report in XML format

Importing JaCoCo coverage report in XML format Version 5.12 of our SonarJava analyzer deprecated uses JaCoCo’s binary format (.exec files) to import coverage. This binary format is internal to the JaCoCo project, and as such there are no guarantees for backward compatibility, so it should not be used for integration purposes. As a replacement, when you scan a project with Sonar scanner, we use a special Jacoco report analyzer, which imports your JaCoCo’s XML coverage report, and this is the pr…

Specifically:

However, the JaCoCo plugin imports coverage reports module by module, so we need to import the same report multiple times (once for every module) to have coverage for all modules. To achieve this we set the property sonar.coverage.jacoco.xmlReportPaths in every module

<properties>
  <sonar.coverage.jacoco.xmlReportPaths>${project.basedir}/../path_to_module_with_report/target/site/jacoco-aggregate/jacoco.xml</sonar.coverage.jacoco.xmlReportPaths>
</properties>
