I've been using Eclipse just fine over the last year now. However, since a couple of days, I'm suddenly not able to run JUnit tests anymore from Eclipse.
This used to work fine: right-click a class > Run As > JUnit Test.
However, now the tests don't run anymore and I'm seeing the following error:
org.junit.platform.commons.JUnitException: TestEngine with ID 'junit-jupiter' failed to discover tests

I've tried reinstalling Eclipse (https://stackoverflow.com/questions/50854359/how-to-uninstall-eclipse), removing the eclipse-workspace/.metadata folder, clearing my .m2/repository, etc.
The tests run fine with Maven. A colleague of mine doesn't have this problem - he can run it from Eclipse fine too.
Any ideas what might be causing this?
Kind regards
Simon

OK, I found the root of the problem and it's a misconfiguration in the MANIFEST:
jupiter bundles must NOT be required bundles, they must be imported packages, e.g.:
Import-Package: org.junit.jupiter.api;version="[5.1.0,6.0.0)",
org.junit.jupiter.api.function;version="[5.1.0,6.0.0)",
org.junit.jupiter.params;version="[5.1.0,6.0.0)",
org.junit.jupiter.params.provider;version="[5.1.0,6.0.0)",
org.junit.jupiter.api.extension;version="[5.1.0,6.0.0)"
