Solutions

1. Address the cause reported by the error message: Jar file the reported value does not exist
2. Verify the inputs, configuration values, and classpath/dependency setup related to this operation, then retry.

Example fix

Correct the condition described ("Jar file the reported value does not exist") and rerun the job or command.

When it happens
