unknown error: DevTools Active Port file doesn't exist java selenium

Question

I am new to Selenium with Java. Followed online tutorial and tried executing the below code but am getting error message

unknown error: DevTools Active Port file doesn't exist java selenium.

I surfed on google and added the options arguments but nothing works.

package mainfiles;

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

public class MainClass {

    static WebDriver driver;        

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        System.setProperty("webdriver.chrome.driver", "E:\\Selenium\\Latest jar files\\chromedriver.exe");
        ChromeOptions options = new ChromeOptions();
        //options.setExperimentalOption("useAutomationExtension", false);
        options.addArguments("--headless");
        options.addArguments("--disable-extensions"); // disabling extensions
        options.addArguments("--disable-gpu"); // applicable to windows os only
        options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
        options.addArguments("--no-sandbox");
        driver =new ChromeDriver();
        driver.get("www.gmail.com");
        }

}

When i run this program, I am getting the below error

Answer 1

this error is due to the incompatible ChromeDriver version and the Chrome browser version that you are using. Please use the latest Chrome driver.exe (v2.41) with the latest Chrome browser version 68. It has worked for me.
