Sonarqube coverage for multimodule projects with integration tests

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>
