Chromedriver is not working when i run in jenkins
Jenkins runs on Centos7
Chromium 78.0.3904.108
version: Google Chrome 79.0.3945.88
location is /usr/bin/google-chrome
location /usr/bin/chromedriver
location chromium is under /usr/bin/chromium-browser

This is my code in eclipse
private void createDriver() {
// Set the Browser from Jenkins, if null, get it from Variables file

this.browser = Variables.browser;
else
this.browser = System.getenv("Browser");
// Set the operating system from Bamboo if not null
if (System.getenv("OperatingSystem") == null)
this.operatingSystem = Variables.operatingSystem;
else
this.operatingSystem = System.getenv("OperatingSystem");

			if (Variables.isIE) {

				// Set IE Driver path
				System.setProperty("webdriver.ie.driver", "src/main/resources/IEDriverServer.exe");

				// Initialize IE driver
				Driver.driver.set(new InternetExplorerDriver());

				// Maximize window
				Driver.driver.get().manage().window().maximize();
			}
	
			
			else {

@HarikaVegesna The initial script is nearly 3 years old, I'm positive there are newer versions of selenium and chromedriver.
You also haven't provided anything indicating an error, and the code you provide is not an issue with the script in this gist.
