Guava NoClassDefFoundErroron Eclipse

Question

I'm trying to use Guava without Maven on Eclipse. I downloaded the JAR file from here and then followed this. However, when I try to run Set<Set<Card>> combos = Sets.combinations(ImmutableSet.copyOf(board),3); where board is an array of objects, I get this exception Exception in thread "Thread-2" java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableSet

My imports are

import java.util.Set; import com.google.common.collect.*;

I get the same error for any other classes from Guava.

My current package looks like this

What am I missing?

are you using gauva-gwt jar if not please remove it ,as per my understanding at runtime this jar is referenced by the jvm — Raushan Kumar, Jan 04 '22 at 16:52
@Raushan Kumar Updated. Do I need to do this step: https://stackoverflow.com/a/4649143/11392406? If yes, where do I find the repository? — DimitrisMel, Jan 04 '22 at 17:07
Or is it the problem that the Source attachment is empty https://imgur.com/5SdLbM4? — DimitrisMel, Jan 04 '22 at 17:32
please try to use direct import com.google.common.collect.ImmutableSet also check if this class is available in jar or not — Raushan Kumar, Jan 04 '22 at 17:38
