I have tried to find solution for my question but seems like no solution have worked yet. Just to mention, im using latest jdk and jre version.

So when im making new java project then i get these 2 errors, its not matter which source i load, all of them gives same error which is weird.

The project was not built since its build path is incomplete. Cannot find the class file for java.util.function.Predicate. Fix the build path then try building this project    oosbrut     Unknown Java Problem

The type java.util.function.Predicate cannot be resolved. It is indirectly referenced from required .class files    GlobalObjects.java  /oosbrut/src/org/brutality/world/objects    line 1  Java Problem

Line 1 : package org.brutality.world.objects;

PS: I have tried all , cleaning project, refreshing, re-opening eclipse etc , also i have removed all libraries and reloaded all of them again.

Would be great if someone can help me out.
