no idea what causes this but saw it on multiple machines

cc @HannesWell maybe you have an idea too

config dialog shows

I think the mere presence of org.hamcrest 3.0 in the target platform causes problems. Hopefully addressed by this pr

https://github.com/eclipse-jdt/eclipse.jdt.ui/pull/1611

Even the emf build broke but I changed this

https://github.com/eclipse-emf/org.eclipse.emf/commit/268292da4d36f4281056e01a20fc37b2389d92e3

Yes that is intended to fix this issue.

But just for clarification, hamcrest 3.0 has to be present in the installation. The JUnit container takes the hamcrest bundle from the installation and not from the TP.

[merks]

I see. That’s a confusing. 🫤

[HannesWell]

I see. That’s a confusing. 🫤

Yes. But one reason is probably that JDT does not know PDE (at least at that place) and therefore has no access to the TP.
