Jenkins Pipeline Build Error -> Test Report Files not found

I receive the following error message when trying to make a build with Jenkins Pipeline. It says that it cannot find the report files. But according to my understanding should these report files not be generated while executing the tests? Locally I can run the tests with mvnw clear test and the files are generated in the target folder (Maven Project). As the target folder contains build files, I dont assume that I have to upload these files to the git Repo? For any kind of help, I would be very happy!
