Can you upload your JAR file somewhere for us to look at?

Not only do you have additional jar files inside your jar file, which is not going to do what you’re hoping, you’ve placed your classes in a package called `ignition.phone.ignitionphone` rather than just `ignitionphone` like you’re referencing in the script.
