Do u have the Guava libraries imported in your classpath? Ensure you have added all the dependency jar files.

Yes, i have imported Guava jar files also, I can able to see Guava jar file under maven dependencies

Hey @Sudarshan, could you please specify the version details of the tools you are using? Maybe there's a version mismatch of version in any of your jar files. Just have a look, just in case!

Hey @Celine, Have you checked the build path configured for your project. There you will see two options 1. Module path 2. Classpath.

Add your all external jars such as selenium jars under classpath not module path and retry. It worked for me.

Also, make sure you have guava libraries imported.
