Java testing initializationError : java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy

Question

My project is composed like this

Project: https://i.stack.imgur.com/Ttx3W.png

when i try to run the tests the error

java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy
 at java.lang.Class.createAnnotationData(Class.java:3521)
 at java.lang.Class.annotationData(Class.java:3510)
 at java.lang.Class.getAnnotation(Class.java:3415)

presents itself.

I have downloaded the right libraries for junit-4 and i believe it has something to do with how the project is built because when i tried to do a test on another simpler project it worked. Maybe I have made a mistake in how I divided my space for my project or maybe I forgot some options on my settings.json file which I'll link down here settings.json

I'll also link my test project which could help identify the problem but it's very messy and unorganized so thanks to anyone that takes the time to help me
