Next to impossible to roll your own build due to no docs being available

[ytcalifax]

As stated, there is literally zero information available on how to build a proper, runnable .JAR file that you can use in a server. Every single time I attempt to run the server after running "gradlew clonePaperRepo" then "gradlew getPaperUpstreamData" and then "gradlew build", a nonworking file with just a MANIFEST appears. If I then run "gradlew createReobfPaperclipJar" or "gradlew createReobfBundlerJar" I do get a working .JAR, but every single time I run it I get this, even with ZERO edits being done. Can someone explain how to generate a proper working file? Or even better yet, is there any possibility for some docs to be created?:

You're supposed to build with ./gradlew createReobfPaperclipJar.

Yes, I managed to figure it out after a few hours of trying by following what the Paper repo instructs users to do.
