You have to give path upto bin folder 🙂 @sunilraju,

Or if your path is set in the environmental variables, then just leave it blank . It will work

If the path is not correct, then it will throw the error as path invalid, but this is a new and strange error. Can you try upgrading or downgrading the JAVA packages @sunilraju

Can you try running JAVA scope alone in your machine @sunilraju?

If it runs without any error, then it is not the issue with JAVA scope
