Getting java.lang.NoClassDefFoundError: com/gargoylesoftware/htmlunit/WebWindowListener when using HTMLUnitDriver

I am trying to use HTMLUnitDriver in my selenium test to understand how HTMLUnitDriver works. Kindly help me with resolving the issue.

I have added the below jars to the build path in eclipse selenium-java-2.53.0 jars TestNG jar

Added the below jars as these were mentioned in other posts as a solution to the error I encountered. However, the issue remains.

selenium-htmlunit-driver-2.52.0 jar selenium-server-standalone-2.53.0

Code:

import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import org.testng.annotations.Test;
public class GoogleSearch {
    @Test
    public void testHTMLUnitDriver() {
        HtmlUnitDriver unitDriver = new HtmlUnitDriver();
        unitDriver.get("https://www.google.co.uk/");
        System.out.println("Title of the page is:" +unitDriver.getTitle()); 
                TestNG Trace is as given below:java.lang.NoClassDefFoundError: com/gargoylesoftware/htmlunit/WebWindowListener 	at GoogleSearch.testHTMLUnitDriver(GoogleSearch.java:13)

                Please take a minute to properly format your code as code and add the error message to the original question and properly format it.
