Error: Invalid or corrupt jarfile while giving webdriver-manager start

Question

When we tried to start the selenium server we are getting this error. It seems the latest selenium server standalone version is 3.7.1. When we updated using webdriver-manager update command it is downloading the version 3.8.0 and when we give the command webdriver-manager start it is throwing the error as

Error: Invalid or corrupt jarfile.

Please see the screenshot attached.

Answer 1

There's a workaround to bring the webdriver-manager version back to 3.7.1 according to this ticket: https://github.com/SeleniumHQ/selenium/issues/5142

1. Update webdriver-manager to 3.7.1

   webdriver-manager update --versions.standalone=3.7.1

2. Rename selenium-server-standalone-3.7.1.jar to selenium-server-standalone-3.8.0.jar. By default this file is in the %YourUserDirectory%\AppData\Roaming\npm\node_modules\protractor\node_modules\webdriver-manager\selenium directory.
