java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.util.Comparator java.util.TreeMap.comparator accessible:module

This is my first cucumber project and i followed a tutorial when setting everything up. It all seems to be the same but for some reason i get this:

java.lang.ExceptionInInitializerError. Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.util.Comparator java.util.TreeMap.comparator accessible: module java.base does not "opens java.util" to unnamed module @74ad1f1f

Any idea how to solve this error ?

Below i have posted everything that comes out in my console as well as my pom file in case there is an issue with my dependencies eventhough the guy from the tutorial's pom file is identical.

This is everything that comes out in my Console.

Solution

  • I solved my problem. Turns out the JRE that eclipse had automatically downloaded and was using wasn't compatible with this version of cucumber. I manually changed the path to a jre 1.8 that i had in my ProgramFilex(x86)/Java folder and now everything works fine.
