title: JUnit import cannot be resolved

  When I try to use the Quick Fix function of the Eclipse, it adds the JUnit 5 to the build path again, although it's already there. All seems to be set up correctly, but it's still not working. I tried cleaning/closing the project as someone suggested in a similar thread. Unfortunately, nothing helped me. Does anyone have an idea on what's going on here?</p>
