Eclipse No Tests Found Using Junit 5 Caused by Noclassdeffounderror for Launcherfactory

The problem

Whenever I run my projects JUnit test (using JUnit 5 with Java 9 and Eclipse Oxygen 1.a) I encounter the problem that eclipse can't find any tests.

The description

Under the run configuration, eclipse can't even find the method which is annotated with @Test, but instead only shows me "(all methods)". The following picture hopefully gives a better glimps of my setup:
