ecilpse/junit5:Test cannot be resolved to a type

Question

My eclipse seems not to be able to resolve JUnit 5 types when I write a test in a Java 9 module:

"Test cannot be resolved to a type"

I manually have added the JUnit 5 Library to the projects buildpath. Also I did these "clean project" and "update eclipse from pom.xml" kind of things.

When I build this project with the embedded Maven there is no problem, the test is compiled and executed.

Is it an eclipse bug in conjunction with java 9 modules or how do i have to configure eclipse correctly?

Configuration:

• eclipse Oxygen.2
• JDK 9.0.1

Answer 1

There are some issues related to Java9 and Junit5 here https://github.com/junit-team/junit5/issues/425

A way out of this is using the support for Oxygen:
