File not found with system classloader.

I am trying to run my program with

java -jar CouchbaseImport.jar

But in the stack trace I get:
INFO: Could not load properties file "cbclient.properties" because: File not found with system classloader.

This is probably a newbie Java question but I am not sure what this error means and how I can modify the artifact generation so that it doesn't happen with IntelliJ. I don't get this error when running from the IDE.

Thank you.
