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

    Debanjan - I had referred the post which you had mentioned and tried all the solutions provided in that but nothing works.. so thought of asking with new post. You can also see in my code that i had updated my code with the correct answer provided in the post which you had referred. Thanks for your understanding. – Samraj Jul 13 '18 at 03:13

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.

@Samraj Downgrading to Chromedriver 2.38 worked for me on Windows 10 Chrome 66.0.3359.181

Just try Downgrading or Upgrading the Chromedriver versions according to the page chromedriver.chromium.org/downloads

And download the corresponding versions from this page chromedriver.storage.googleapis.com/index.html
