If it generates a lot of code, then yes. But it may also just generate 2-3 lines of boilerplate code that's very annoying to keep typing over and over.
This is all boilerplate and can easily take half a minute. How am I doing things wrong? Are you saying there's an easier way?
Or I can just type something like "./script/generate class Foo Bar" and be done with it and save like 15 seconds.
