Answer 1

This error message...

Invalid port. Exiting...
?? ??, ???? ??:??:?? ????????? org.openqa.selenium.os.OsProcess checkForError
SEVERE: org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1)

...implies that the OsProcess is unable to bind to the assigned free port within your system.

As per the discussion Getting Invalid port error. and Invalid port. Exiting...

"Invalid port. Exiting..." occurs when the port assigned to chromedriver is less than 0 or greater than 65535.

Solution

• Execute netstat command through CLI to see if you have reached limit of possible open connections or check if there is another application running on the given port.
• Check your firewall settings, there is a good chance that firewall configuration may be causing the issue.
• Upgrade ChromeDriver to current ChromeDriver v2.38 level.
• Keep Chrome version at Chrome v66.x levels. (as per ChromeDriver v2.38 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot to free up the ports.
• Execute your @Test.

Note : Steps 1, 2, 7 and 8 are vital to debug/solve the issue you are currently facing.

Answer 2

Check whether the driver location is correct. I am able to launch Facebook without any issue.

package Practice;

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

public class Facebook 
{

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

        System.setProperty("webdriver.chrome.driver", "./drivers/chromedriver.exe");


        WebDriver driver=new ChromeDriver();

        driver.get("http://www.facebook.com");


        driver.manage().window().maximize();

    }
}
