Answer 1

I think this might come from a difference of version from the JDK or javac. Maybe you should check that you're using the same JDK version on your desktop than on Heroku, and if not, change it accordingly on your laptop. Hope this help !

This error appear because of this 2 things. We should use ":" for unix, and ";" for windows in the arguments line from the start up command.
