Encountering a problem when attempting to execute Selenium

Currently, I am utilizing Ubuntu 12.04 and attempting to execute Selenium by running the command

webdriver-manager start

However, every time I try to run it, I encounter the following error message:

webdriver-manager start
seleniumProcess.pid: 3522
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/openqa/grid/selenium/GridLauncher : Unsupported major.minor version 51.0
    at java.lang.ClassLoader.defineClass1(Native Method)
    ...
Selenium Standalone has exited with code 1

I initially installed it using the following commands:

sudo npm install –g protractor
webdriver-manager update

Could someone please provide guidance on how to resolve this issue and successfully launch the Selenium server?

Answer №1

If you are experiencing an unsupported major.minor version error, it is likely because you are running a java program that was compiled with a newer java version than the one you have installed. Chances are, the selenium version you are using has been compiled from a newer java version compared to your current java version.

Make sure to verify your java version and consider upgrading to the latest java version available.
