ship install fails with AssertionError when called with no arguments #7
Description
This error is very user-unfriendly, and makes it look like a bug:
$ ship install
nested exception is java.lang.AssertionError: Expression must be true.
Unexpected exception!! Report the bug to [email protected]
but in fact it just expects between 1 and 3 arguments. So it should display a helpful message on correct usage.
