Build Error Jenkins : org.openqa.selenium.WebDriverException: Timed out waiting for driver server to start

Im trying to build a project maven for automationg testiong the scenarios working fine when i excute them on local but when i try to build the job I got this error
i already added the chromedriver, the build is on a vm Linux i added the chromedriver for Lunix too
I downloaded the last version of chrome driver.
Thanks

It may be caused by following reasons,
In linux/vm we need to provide executable/higher permission on chrome driver.
chmod 777 chromedriver
if you connecting to remote driver, we need to do port connectivity between machines.

Compatibility chromedriver and selenium with the last version of chrome? [duplicate]

when i go to command prompt and type chromedriver -v:
ChromeDriver 79.0.3945.36 (3582db32b33893869b8c1339e8f4d9ed1816f143-refs/branch-heads/3945#{#614})
but when i try to run this code :
from selenium import webdriver
class InstaBot:
def __init__(self):
self.driver=webdriver.Chrome()
self.driver.get("www.instagram.com")
InstaBot()
it gives me error like this:
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 80
why this is happening i tried to remove selenium as well as chromedriver
and reinstall of version 79.0.3945 but when i run it ,it show this can only be run on version 80
my chrome version is 79.0.3945 which is lastest ,and version 80 chrome is chrome beta

This error message...
selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 80
...implies that the ChromeDriver v80.0 was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
You mentioned about using chromedriver=79.0.3945.36 and the release notes of chromedriver=79.0 clearly mentions the following :
Supports Chrome v79
Presumably you are using chrome v79.0 browser.
So, it's quite evident your have chromedriver=80.0 present within your system which is also within the system PATH variable and is invoked while you:
self.driver=webdriver.Chrome()
Solution
There are two solutions:
Either you upgrade chrome to Chrome Version 80.0 level. (as per ChromeDriver v80.0 release notes)
Or you can override the default chromedriver v80.0 binary location with chromedriver v79.0 binary location as follows:
from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')
You can find a detailed discussion in Ubuntu: selenium.common.exceptions: session not created: This version of ChromeDriver only supports Chrome version 79
Additional Considerations
Ensure to:
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your #Test as non-root user.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

Use Bonigarcia plugin in project. After that it will manage all driver by itself.It reads chrome version and instantiate driver accordingly.

WebDriverException: Failed to connect to binary FirefoxBinary(C:\Program Files\Mozilla Firefox\firefox.exe) with GeckoDriver Firefox and Selenium Java

Using Selenium 3.1.0, firefox latest version 72.0, default firefox driver 2.53.1
here is my code
System.setProperty("webdriver.gecko.driver" ,"C:\\Users\\sindhusha.tummala\\Downloads\\geckodriver.exe");
driver = new FirefoxDriver();
Still i am getting the error
org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(C:\Program Files\Mozilla Firefox\firefox.exe) on port 7055;
Could any one help with this

This error message...
org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(C:\Program Files\Mozilla Firefox\firefox.exe) on port 7055;
...implies that the GeckoDriver binary (executable) was unable to initiate/spawn a new Browsing Context i.e. Firefox Browser session as it was unable to locate the FirefoxBinary.
This issue arises when Firefox is not installed at the default location or is not installed at all.
Solution
To solve this issue:
If Firefox is not al all installed you have to install it.
If Firefox is not installed at the default location you need to pass the absolute path of the Firefox binary through the argument firefox_binary as follows:
Code block:
public class A_Firefox_binary
{
public static void main(String[] args)
{
System.setProperty("webdriver.gecko.driver", "C:/Utility/BrowserDrivers/geckodriver.exe");
FirefoxOptions options = new FirefoxOptions();
options.setBinary("C:\\path\\to\\firefox.exe");
WebDriver driver = new FirefoxDriver(options);
driver.get("https://stackoverflow.com");
System.out.println("Page Title is : "+driver.getTitle());
driver.quit();
}
}
Additional Consideration
Ensure that:
Upgrade JDK to recent levels JDK 8u222.
Upgrade Selenium to current levels Version 3.141.59.
Upgrade GeckoDriver to GeckoDriver v0.26.0 level.
GeckoDriver is present in the desired location.
GeckoDriver is having executable permission for non-root users.
Upgrade Firefox version to Firefox v70.0 levels.
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
(WindowsOS only) Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
(LinuxOS only) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint 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.
Execute your Test as a non-root user.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

Possible causes are invalid address of the remote server or browser start-up failure.
Can any one please help?

#jyothi B please run following two commands
/usr/bin/safaridriver --enable
/usr/bin/safaridriver -p 0
and then start your tests.

Why am I getting a org.openqa.selenium.firefox.NotConnectedException exception?

Yesterday I used Eclipse to run a Java program that used the Selenium API and Firefox as the browser. Today I made some modifications to the program and, when I try to run it, I get:
org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
followed by many more lines of text.
This is thrown by the first line of code that is executed in the program. I have made no changes to versions of Eclipse or Firefox, and the Selenium build path for the program is the same. So why is the exception thrown?
