Test coverage for QuarkusUnitTests in an extensions deployment module? (Gradle)

[HerrDerb]

When writing a quarkus extension with gradle, I would like to have full code coverage.
The code coverage with jacoco does work for unit tests.
The only thing is that all tests in the deployment module run with QuarkusUnitTest seem not to add to the total test coverage, leading to a wrong total coverage.

How do I need to configure jacoco in a quarkus extensions to get the combined coverage of junit tests and QuarkusUnitTest?
