Could not run component tests in Eclipse

we are using cucumber java for implementing component tests in our project.below is the test runner class.

import org.junit.runner.RunWith;

import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@Cucumber.Options(format={"pretty"})//, features="classpath:component/features/*.feature")
public class RunAllComponentCukesTest {
}

When I run component tests through this class,it was working fine.Now its not.I don't know whats wrong with this.I thought it might be with class path issue.I changed path and I just run all tests but in any way it's not working.If run from command prompt it is working fine.

I am getting following error message:

I searched in google but this problem looks more generic so couldn't get the answer.

Got to Help/About Eclipse, click on "Installation Details". Select "Cucumber Eclipse Feature" and click in "Update...". Don't worry if your plug-in is up to date...

Now open your POM file (Maven Project) and set artifacts "cucumber-java", "cucumber-jvm" and "cucumber-junit" to version 1.2.2 at least (junit must be at least 4.11).

This is an old question but just in case anyone happens to land here the solution is to use cucumber-junit 1.2.2

I started getting this error seemingly out of the nowhere as well.

Problem: It looks like there is an incompatibility between cucumber.runtime.junit.ExamplesRunner and org.junit.validator.PublicClassValidator from junit-4.12-beta-1.jar.

PublicClassValidator throws an Exception with message:

"The class cucumber.runtime.junit.ExamplesRunner is not public."

I was only able to see this message displayed by stepping through with the debugger.

I was importing the latest 4.+ version of junit which is currently 4.12-beta-1. That is why the problem seemed to come out of nowhere. I guess I had not refreshed my dependencies in a while.

Solution: I reverted back to junit-4.11.jar and the error is no longer happening.
