Question

I have a project with multiple modules.

• module1
• module2
• module3
• testModule:
  • src/main/java:
    • com.example.test
      • some legacy I cannot get rid of
  • src/test/java:
    • com.example.test:
      • actual test classes pom.xml (in testModule)

pom.xml(root pom)

content of testModule pom:

A coverage report is generated, but only containing the tests in testModule/src/main/java. The tests in testModule/src/test/java are not part of the report.

Does anyone know how I can add this folder so the reports cover all the tests?

versionJacoco: 0.8.8 surfire: v3.0.0-M7

I tried using

testSourceDirectory

and

includes
