Getting error "java.lang.NoClassDefFoundError: com/gargoylesoftware/htmlunit/html/HtmlElement"

Question

I am using selenium webdriver for the testing I have written code:

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.MarionetteDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
//import org.openqa.selenium.firefox.FirefoxProfile;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
//import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;


public class sample_google
{

 WebDriver driver;


    @BeforeTest

    public  void setUp(){

       // FirefoxProfile profile = new FirefoxProfile();
     //System.setProperty("webdriver.gecko.driver", "D:\\ashwini\\geckodriver.exe");
     
//    driver= new MarionetteDriver();
      driver = new HtmlUnitDriver();

     driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    }


    @Test

    public void testLoadingFirstPage() throws Exception{

        driver.get("https://www.google.com/");
        WebElement searchBox = driver.findElement(By.name("q"));
        searchBox.sendKeys("fast cars");
        searchBox.submit();
        System.out.println("Page title : " + driver.getTitle());
        WebElement resultCount = driver.findElement(By.id("resultStats"));
        System.out.println("Result Count : " + resultCount.getText());
       

    }
    @AfterTest
   public void teardown()
   {
    //driver.quit();
   }

    
}

However I am getting output

I have included the jar of selenium-htmlunit-driver-2.46.0.jar in the code. Still getting the error. So please check what is the issue.

Thanks in advance

I have included the jar of selenium-htmlunit-driver-2.46.0.jar separately in the libraries. still getting the error

@Ashwini.J Are you running the code from Eclipse, IDEA etc? Or are you using the command line? — Grasshopper, Aug 30 '16 at 08:28

Add below dependency to your pom.xml file and it should work fine

<groupId>org.seleniumhq.selenium</groupId>
<artifactId>htmlunit-driver</artifactId>
<version>2.20</version>
</dependency>

Since 2.53 this is no longer shipped with webdriver

If you are using Selenium main distribution package version 2.53 or later then you should add HtmlUnitDriver separately, it's no longer bundled with the standalone jar file.

If you are using Selenium 2.52 or earlier you don't need to download and install HtmlUnitDriver, it is already there.

Please make the changes accordingly, it should work fine. Learn more.
