java.lang.NoClassDefFoundError: org/openqa/selenium/remote/service/DriverService$Builder - eclipse

Question

I am trying to create a TestNg Maven project in Eclipse for Selenium. Here is my code :
package Edureka_Case_Study_8th.Edureka_Case_Study_8th;
import org.testng.annotations.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class CaseStudy2 {
#Test
public void basicSetup() {
System.setProperty("webdriver.gecko.driver", "C:\\Users\\Sitesh\\Selenium\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.flipkart.com/ ");
}
}
When I try to run it, I get the following error:
[RemoteTestNG] detected TestNG version 7.3.0
FAILED: basicSetup

Its look like issue is with Selenium Libraries. Please add all selenium jars. Follow below:
Download Selenium Client & WebDriver Language Bindings for Java from (Make sure you are downloading as per your system configuration) https://www.selenium.dev/downloads/
Unzip the file.
Open your project > Right click > Build Path > Configure Built Path > Libraries > Add External Jars
Select all jars present inside above unzipped folder ( Make sure you add libs also).
Also insure Java is installed and path for JDK is pointed under execution environment.
Go to Build Path > Configure Built Path > Libraries.
Open JRE System Libraries
And if by default selected environment is not pointing to JDK. Select Alternate JRE.
Click on Installed JREs and browse to JDK folder select.
Note : Using Same Code and above mentioned SetUp I am able to run your script.
