Bump

Do not bump your thread, first. Second, you are managing your dependencies incorrectly.

So i tried to add minecraftLibrary 'net.dv8tion:JDA:5.0.0-beta.8' but:

Could not find method minecraftLibrary() for arguments [net.dv8tion:JDA:5.0.0-beta.8] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

Ah, I missed the unsupported version. Apologies, but

The version you are using is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.

Currently supported versions are 1.19.4 (Latest) and 1.18.2 (LTS).
