Compile and test with java 11 and jupiter

I’m trying to use your plugin in a multi project but I can’t run tests in eclipse. Running tests via Gradle works good.
This is the project example: multiProjectA.zip (62.1 KB)
When I try to run tests in api, eclipse asks for junit 5.
Also, I cant understand if I should put apply plugin: 'com.lingocoder.mrjar' in allprojects or in subprojects.

I’ll share the question as soon as I create it, I can’t create a good topic right now.
