Description
If you run the command line generator with one option of help, it throws a NullPointerException when it can't find the second option.
java -jar openapi-generator-cli.jar help
Ideally it would return a list of options that help will work with, such as generate. (I have no idea what other options you can provide the help command, hence a list would be nice).
