I keep getting this error: java.lang.NoClassDefFoundError: org/openqa/selenium/WebDriver using Selenium trying to open Chrome

I am getting a complilation error when I try to run Selenium Webdriver.
I am using Eclipse and Java inside Eclipse.
I:
Went ahead and downloaded Selenium Server (4.3.0), the language-specific client drivers Java (4.3.0), and the stable release of the latest chrome drivers (got it from here - https://chromedriver.storage.googleapis.com/index.html?path=103.0.5060.134/). I had to download the 32 bit version even though my computer is 64 bit, but I only saw a 64 bit version for Windows.
Configured build path and added external jars to build path from the Selenium server file I downloaded.
The code:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class FirstSeleniumTest {
WebDriver driver;
public void launchBrowser() {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\zachw\\Desktop\\Selenium\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
driver.get("https://www.amazon.in/");
}
public static void main(String[] args) {
FirstSeleniumTest obj = new FirstSeleniumTest ();
obj.launchBrowser();
}
}
}
and keep getting this error:
Error: Unable to initialize main class FirstSeleniumTest
Caused by: java.lang.NoClassDefFoundError: org/openqa/selenium/WebDriver
Can anyone tell me why I am getting this compilation error and how to fix it?

How do I setup Selenium WebDriver with Java?

I have a question on how to start using Selenium WebDriver with Java.
Here is my code:
package newpackage;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class MyClass
{
public static void main (String[] args)
{
WebDriver driver = new ChromeDriver();
driver.get("http://google.com");
}
}
I then get the following error:
Error occurred during initialization of boot layer
java.lang.module.FindException: Error reading module: C:\Users\MrJPG\eclipse-workspace\Project IG Bot\bin
Caused by: java.lang.module.InvalidModuleDescriptorException: Package IGBotPackage not found in module
Does anyone know the solution to this? I have tested adding the external jars from Selenium in both the Modulepath and Classpath. However, both seem to have the same result and error.

you need add this
System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://google.com");
chromedriver.exe is your chromedriver.exe path //download chromedriver.exe
maybe
System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
Need to be the same as your chrome version
if your chrome is '80.0.3987.106'
need at least these are the same '80.0.3987'
Hope that helps you

Please use Which ChromeDriver version is compatible with which Chrome Browser version? to download right version of chromedriver exe.
Place above exe in any(e.g. D:\) path and use below code:
System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://google.com");

Can somebody explain why Selenium simple program is not working ? (On Mac using Maven-Java)

I'm new to Selenium and I can't run the simplest program:
public static void main(String[] args) {
WebDriver driver = new ChromeDriver();
driver.get("https://google.com");
HelloWorld.LOGGER.info(driver.getTitle());
}
The error I receive :
Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver.

After reading the exception above I saw in this website a solution that didn't work for me :
public static void main(String[] args) {
System.setProperty("WebDriver.Chrome.driver","/Applications/Google\\ Chrome.app/Contents/MacOS/Google\\ Chrome");
WebDriver driver = new ChromeDriver();
driver.get("https://google.com");
HelloWorld.LOGGER.info(driver.getTitle());
}

I'm working on MacOS - Catalina, my IDE is Intellij and this is a Maven Project.
Tried to switch the second argument of System.setProperty() function to numerous variations of the path with no success.
What am I missing ?

To run your code on chrome browser you need to set path of chromedriver. ypu haavee specified wrong path of chrome driver in your code
System.setProperty("webdriver.chrome.driver","chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("https://google.com");
System.out.println(driver.getTitle());
Check your browser version and download chromedriver from the below link:
https://chromedriver.chromium.org/downloads

So, my friend here above #Rock was right.
I did need to download the chrome driver.
But, because I'm working on macOS Catalina, I had to change the permission for the chromedriver file manually.
With the help from this issue : MacOS Catalina(v 10.15.3): Error: “chromedriver” cannot be opened because the developer cannot be verified. Unable to launch the chrome browser
This is how the code looks like now :
public void firstTest() {
System.setProperty("webdriver.chrome.driver","/Users/raziv/Downloads/chromedriver");
WebDriver driver = new ChromeDriver();
driver.get("http://google.com");
System.out.println(driver.getTitle());
}
And it's working fine

Selenium Browser Drivers can't be configured through System Property when referenced through Class Objects

Selenium Browser Drivers can't be configured through System Property when referenced through Class Objects.

Sometime this happens:)-
Replace this
System.setProperty("webdriver.firefox.driver","C:\\Utility\\BrowserDrivers\\geckodriver.exe");
with
System.setProperty("webdriver.gecko.driver","C:\\Utility\\BrowserDrivers\\geckodriver.exe");
Hope this helps. Thanks.

Use gecko.driver in place of Firefox.driver like this:
System.setProperty("webdriver.gecko.driver","E:/Gecko/geckodriver.exe");

System.setProperty("webdriver.firefox.driver","C:\\Utility\\BrowserDrivers\\geckodriver.exe");
need to be replaced by
System.setProperty("webdriver.gecko.driver","C:\\Utility\\BrowserDrivers\\geckodriver.exe");
as the driver exe has been replaced by gecko however classname is still FirefoxDriver.

Unable to open Firefox browser with given URL using Java on eclipse

I am new in Automation testing.
Had created a simple program to Open URL in Firefox browser. Browser is getting opened without URL.
Someone please help.
package sanitytest;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Adminlogin {
public static void main(String[]args){
WebDriver driver = new FirefoxDriver();
driver.get("http://www.gcrit.com/build3/admin/login.php");
}
}
I am using Firefox version :- 47.0.1
eclipse mars version :- 4.5.0
Selenium webdriver version :- 2.51

For Mozila Firefox till version 46.x it was the legacy browser and we didn't need gecko driver. Mozila Firefox from version 47.x onwards comes with Marionette, which is an automation driver for Mozilla's Gecko engine. It can remotely control either the UI or the internal JavaScript of a Gecko platform, such as Firefox. Can be donwloaded here: https://github.com/mozilla/geckodriver/releases and needs selenium 3.x.
So, either downgrade FF to version 46.x, or use latest selenium binding with geckodriver + latest FF

Unfortunately Selenium WebDriver 2.51.0 is not compatible with Firefox 47.0. The WebDriver component which handles Firefox browsers (FirefoxDriver) will be discontinued.
Try using firefox 46.0.1. It best matches with Selenium 2.51
https://ftp.mozilla.org/pub/firefox/releases/

try the following code its working
package automation ;
import java.util.concurrent.TimeUnit
enter code here
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class test {
public static void main(String[] args) throws InterruptedException {
//Object webdriver;
System.setProperty("webdriver.gecko.driver",
"C:\\Users\\user\\Downloads\\geckodriver-v0.17.0-win64/geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(25, TimeUnit.SECONDS);
driver.get("https://www.easybooking.lk");
String i = driver.getCurrentUrl();
System.out.println(i);
//driver.close();
}
}
if its not working http://www.seleniumhq.org/download/ here download java 3.4.0
then in eclipse, right click your project-->properties-->java build path--> liberies-->add external JARS..
