test Grails 3.3.8 app with junit 4 or 5 in eclipse 2018-12, is it possible?

Question

i m working on a grails project and i want to add tests to it. I used spock and Geb but i prefer JUnit but it doesnt work.

i m creating a new Groovy Test with the eclipse wizard, i select either junit4 or junit 5 then it creates a new test class

i right click and select run as> Junit Test it should show the junit view with failing test but no i get a lot of "Invalid package binding for default import java.util/net/io" and a "could not retrieve superclass","AbortCompilation ... AssertionError cannot be resolved. it is indirectly referenced from required .class file" from org.eclispe.jdt.core

and i get an invocationTargetException caused by a NPE from org.eclispe.jdt.junit

those are my last errors from my many attempts, i feel like it s just impossible to do it.

if someone managed to make it work, pls tell how you did it

regards

Yes, it is. There are numerous ways to do that.

A common way to do that is to create a launch config in Eclipse that will execute the test or integrationTest Gradle task with the appropriate parameters.
