Here is the image of my project structure:

And here is my RunIT.Java Class

package com.Cucumber;

import org.junit.runner.RunWith;

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;


@RunWith(Cucumber.class)
@CucumberOptions(
        tags={"@mysingle"},
        features = {"."})
public class RunIT {

}

Answer 1

It looks like you're missing the cucumber-core library.

Try adding the following to your dependencies.

    <dependency>
        <groupId>info.cukes</groupId>
        <artifactId>cucumber-core</artifactId>
        <version>1.1.8</version>
    </dependency>

Also, you appear to be mixing and matching versions. Try using the same version for all the cucumber-* libraries.
