Java JaCoCo integration report in multi-module project

[Shalom Annan]

My project has the following structure as shown below. My integration tests are in module A and it uses classes in other modules. I want JaCoCo to include the code-coverage of the other modules that are executed by module A.

I understand that the plugin can merge reports of other modules, but this is an different scenario. I'm executing the integration-test on module A
