问题
I'm using Java 9.0.4 in Eclipse Oxygen.3a
JUnit 5 is on the modul-path and required in the module-info.java.
When I try to run my code i always get the following message:
Error occurred during initialization of boot layer java.lang.module.FindException: Unable to derive module descriptor for C:\Users\Tim HP.p2\pool\plugins\org.junit.jupiter.migrationsupport_5.0.0.v20170910-2246.jar Caused by: java.lang.module.InvalidModuleDescriptorException: Provider class org.junit.jupiter.engine.JupiterTestEngine not in module
I cannot really figure out how I can resolve this issue.

You need to upgrade to junit 5.0.2 (or later)
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=525948#c12 and https://bugs.eclipse.org/bugs/show_bug.cgi?id=525948#c19
The current Eclipse Photon milestone builds (which are feature-complete) already contain JUnit 5.1. You can download the 4.8RC1 SDK package from http://download.eclipse.org/eclipse/downloads/ or other 4.8M7 packages later today from https://www.eclipse.org/downloads/index-developer.php. In case you find bugs, please report them at https://bugs.eclipse.org
