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
    at org.openqa.selenium.remote.internal.HttpClientFactory.getClientConnectionManager(HttpClientFactory.java:69)

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

Best answer

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.

This worked for me as well. I removed all the jars from the "Module Path" and added again to the "Class Path" and ran the first test of the launching Chrome successfully. Thanks- Shraddha

Hi,

Where can I get the Module path and build path in the above said window.

commented Apr 13, 2020 by anonymous

You need to right-click on your project's name and go to "build path" in your eclipse IDE.

javax.crypto package is included in jce.jar, which can be found under the "lib" folder of your JRE. Add it to your classpath, and you should be fine.

For more information about classpath, see: http://docs.oracle.com/javase/7/docs/technotes/tools/windows/classpath.html

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.
