InitializationError in JUnit Test Cucumber ( NoClassFound - IGherkinDialectProvider )

Question

I'm creating Cucumber Project for the first time. I'm using Eclipse. I've not created Maven project.I'm following some tutorials and created Java Project.Where I added JAR files manually. List of JAR files: cucumber-core-4.0.0.jar cucumber-java-4.0.0.jar cucumber-junit-4.0.0.jar cucumber-jvm-deps-1.0.6.jar gherkin-6.0.0.jar junit-4.12.jar mockito-all-1.10.19.jar

I've created Feature File : Feature: Google Homepage This feature verifies the functionality on Google Homepage

Scenario: Check that main elements on Google Homepage are displayed
Given I launch Chrome browser
When I open Google Homepage
Then I verify that the page displays search text box
And the page displays Google Search button
And the page displays Im Feeling Lucky button 

I've created TestRunner Class

package testRunners;

import org.junit.runner.RunWith;
import cucumber.api.junit.Cucumber;
import cucumber.api.CucumberOptions;

@RunWith(Cucumber.class)
@CucumberOptions(,features="resources/features", glue="")
public class TestRunner_FirstScenario {
}

I try to run this class as JUnit Test. Then I get error,I'll add error at the end of the post.

I don't think the reason is that I don't have StepDefinitions class.I think there are some compatibility problems with JAR versions, but I'm using the newest versions.

Error is:

TestRunner_FirstScenario
testRunners.TestRunner_FirstScenario
initializationError(testRunners.TestRunner_FirstScenario)
java.lang.NoClassDefFoundError: gherkin/IGherkinDialectProvider

If you check the POM of cucumber on maven central you can see that it has a dependency on Gherkin 5.1.0 rather then 6.0.0.

https://search.maven.org/artifact/io.cucumber/cucumber-jvm/4.0.0/jar

I would recommend that you use a tool for dependency management rather then manually collecting jar files. Both maven and gradle are excellent choices.
