It appears that the jarSign step is now mandatory when running build which can be a bit annoying for people who don't have a keystore setup (it fails without it).

I advise making the jarSign reverse-depend on build so you can still sign the jars but running only build just won't sign them.

This way, you will still be able to sign your jars when you want (gradle jarSign) and others who compile from source can normally build DS (gradle build).

PS: I hope but am not sure if you can make jarSign depend on build.

I will take a look. It looks to be a straight forward tweak, but I am a real gradle noob so anything it possible. :)

Posted JARs to CurseForge, though this really doesn't have anything to do with that. :)
