Selenium WebDriver Setting debuggerAddress Stopped Working

I'm using Selenium Web driver, however, I am preloading a browser by setting the debuggerAddress. I connect through a specified port. I had this working great. Suddenly, it's stopped working. I'm not quite sure what the issue is.
public void launchBrowser() throws InterruptedException {
try {
// Set file path of chrome driver
System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe");
// Start chrome driver with existing chrome browser
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("debuggerAddress","localhost:1250");
// Create object
driver = new ChromeDriver(options);
// Write to console where we are
System.out.println(driver.getCurrentUrl());
}
catch(Exception e) {
console("JacksClass.java","launchBrowser()", "Exception: " + e);
}
}
Before I run the script. I start the Chrome browser with this command in CMD
start chrome --remote-debugging-port=1250
After launching the browser from CMD successfully. Then running the code. I get the following exception after around 1-2 minutes.
JacksClass.java - launchBrowser() : Exception: org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

Driver info: driver.version: ChromeDriver
All of this was working great a month ago. I have the chrome driver installed in the same location.

Finally got it to work. Firstly I tried to access the open port in another browser.
Typing localhost:1250 into the URL bar.
It could not connect. So there clearly was an issue with that port. I have tried many different ports but still had the same issue.
I finally tried port 1258 and then double-checked it with the test outlined above. Typing localhost:1258 into another browser proved the port was active.
Then my program worked as well! How strange! Glad it's working now :)

Java - Unable to get the latest Edge/Chromium release working with selenium

We have a set of Selenium auto tests that work with Chrome/Firefox/Edge (pre Chromium Edge). We would like to be able to run the set test suite against the latest edge.
Selenium (Java) - 4.0.0-alpha-4
Edge - 79.0.309.71
I've tried various combinations of the below setup
System.setProperty("webdriver.edge.edgehtml", "false");
System.setProperty("webdriver.edge.driver", "path\to\msedgedriver.exe");
System.setProperty("webdriver.chrome.driver", "path\to\msedgedriver.exe");
EdgeOptions edgeOptions = new EdgeOptions();
edgeOptions.setBinary("path\to\msedgedriver.exe");
driver = new EdgeDriver();
Each time gives the following error
org.openqa.selenium.WebDriverException: Timed out waiting for driver server to start.
Build info: version: '4.0.0-alpha-4', revision: 'c2d955b49e'
System info: os.name: 'Windows 10', os.arch: 'amd64', os.version: '10.0', java.version: '1.8.0_162'
Driver info: driver.version: EdgeDriver
Has anyone got this working?

I test with Microsoft Edge(Chromium) Beta version 79.0.309.43 and the same version of Microsoft Edge(Chromium) WebDriver (You could download the webdriver from here) and it works. You could refer to the code below and change the path to your owns:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.edge.EdgeOptions;
public class Edgeauto {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "your\\path\\to\\edge\\webdriver\\msedgedriver.exe");
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setBinary("C:\\Program Files (x86)\\Microsoft\\Edge Beta\\Application\\msedge.exe");
EdgeOptions edgeOptions = new EdgeOptions().merge(chromeOptions);
WebDriver driver = new ChromeDriver(edgeOptions);
driver.get("https://www.google.com/");
}
}
Also please remember to have the location of Edge Beta and msedgedriver.exe on your PATH.

Not sure if this will be relevant for everyone, but I have fixed it myself by doing the following...
The version of edge is Version 79.0.309.71 (Official build) (64-bit) and i assumed the correct driver was the the 64 bit driver from the microsoft site.
HOWEVER, I then tried the 32 bit driver and it worked as expected...
System.setProperty("webdriver.edge.driver", "path\to\msedgedriver_32.exe");
driver = new EdgeDriver();

Eclipse is not able to find chrome library

ChromeOptions options = new ChromeOptions();
options.setBinary("C:\\Program Files (x86)\\Google Chrome (Local)\\chrome.exe");
WebDriver driver = new ChromeDriver();
String baseUrl = "http://www.facebook.com";
String tagName = "";
driver.get(baseUrl);
tagName = driver.findElement(By.id("email")).getTagName();
System.out.println(tagName);
driver.close();
System.exit(0);
}
}

make sure all selenium jars are not missing in your project. If not delete them anyway and add new jars from fresh download
clean your project
as pcalkins advises, use the chrome options propertly

org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session in Mac

I am fairly new to selenium and trying to invoke the Firefox browser using the following java code.
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class google {
public static void main(String[] args) throws InterruptedException {

System.setProperty("webdriver.gecko.driver", "/Users/gowtham/Desktop/Selenium/geckodriver");
WebDriver driver = new FirefoxDriver();
driver.get("http://google.com");
Thread.sleep(1000);
driver.quit();
}
}
When I run the above code, I get the following exception on my console.

I have firefox v52.0 installed on my machine.
Please share your thoughts on this issue.

I can't add comments so far, so post the way to resolve this problem here.
Indeed, gecko driver version needs to be downgraded.
For those, who are using 'bonigarcia-webdrivermanager', add driver version explicitly before instantiating FirefoxDriver:
FirefoxDriverManager.getInstance().setup("0.14.0");

While initiating the ChromeDriver getting an exception

I'm very new to Selenium. Below given is my first test script.
Question: Does it require selenium server to test a local website (which is hosted in the same machine as the test scripts being run).
Also tried executing the same script from Internet Explorer also, still getting the same.
It just opens the browser and closes(because of finally block) it.
import org.openqa.selenium.chrome.ChromeDriver;
public class TestScript {
/**
* #param args
* #throws InterruptedException
*/
public static void main(String[] args) {
ChromeDriver driver = null;
try
{
System.setProperty("webdriver.chrome.driver", "C:\\Users\\user1\\AppData\\Local\\Google\\Chrome\\Application\\chrome.exe");
driver = new ChromeDriver();
System.out.println("Opening the Browser");
driver.get("http://localhsot:5080/myWebSite/8450191#");
System.out.println("Open the Browser");
System.out.println("");
System.out.println("Title" +driver.getTitle());
}
catch (Exception ie)
{
ie.printStackTrace();
}
finally
{
System.out.println("Quitting the Browser");
driver.close();
driver.quit();
}
}
}

You are getting a little confused about what you need to point Selenium to.
Here:
System.setProperty("webdriver.chrome.driver", "C:\\Users\\user1\\AppData\\Local\\Google\\Chrome\\Application\\chrome.exe");
This setting, webdriver.chrome.driver is a setting that Selenium will read to find out where the ChromeDriver is located, not the actual Chrome installation.
https://code.google.com/p/selenium/wiki/ChromeDriver
You must download the ChromeDriver and where it is located should be what you pass in for the webdriver.chrome.driver property.
I imagine it's the same reason when you try with IE, it also requires a driver which I guess you don't have:
https://code.google.com/p/selenium/wiki/InternetExplorerDriver
In terms of whether you need a "server" -> for your tests, no, you are not running them remotely. Once you decide to run them remotely (i.e use the RemoteWebDriver instead of ChromeDriver) then you will need the Selenium server.

I would recommend instead of using System.setProperty() to put your drivers in the same folder and point to that folder in System Variables Path. Then you don't need to point to it at all in code and updating your driver won't require a code rewrite.
