Selenium Webdriver Java - Eclipse java lang NoClassDefFoundError

Question

I have installed java and eclipse, and downloaded the JARS and placed them in the right directory as it should be. Below is my script:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class myClass {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.out.println("Hello\n");

        System.setProperty("webdriver.chrome.driver", "C:/Selenium/Drivers/chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("https://www.facebook.com");
    }
}

And i get the below error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/config/RegistryBuilder

This is my first script and i'm getting an error even though its basic. Can someone plz help?

Hey there, you can first check which version of ChromeDriver is supported by Chrome Browser. You can simple google which version of ChromeDriver is supported by Chrome Browser version-76.

Then you can delete previously installed ChromeDriver.exe file and install the supported version. — Abha, Jul 26, 2019

I also faced this issue first time, in order to solve this I checked build path configured for my project.There you will see two options 1. Module path 2. Class path

Add your all external jars such as selenium jars under class path not module path and retry. It worked for me and If you need to know more, join our Selenium Training Online.

java.lang.NoClassDefFoundError is usually thrown when the installed JRE cannot find the Class which needs to be executed.

Also, the required imports and JARS would also not be available. It seems like you have tried to add the jars related to Java Client. So the only solution is to remove and place all the JARS again correctly.
Do th following:

Remove all JARS including Selenium standalone server & Selenium Java client
Import all the JARS which you downloaded from here: https://www.seleniumhq.org/download/.
Make sure to import them to "Add External JARS" from "Conigure Build Path" option in Eclipse IDE.

This has to definately work.

Do we need to add all the jars that show up in the lib directory? I am talking about the lib directory that is included in the zipped Selenium 4 build (4.2.2)
