Things to Know
The minecraft variants of library depend on recent spigot/bungeecord/velocity versions. That means it may not work as expected or may not work at all on older server versions. You will not receive any support, when using another server version than the one this library is built for.
If you want to use older server versions, consider a cross-version compatibility tool, like ViaBackwards, ViaRewind or ProtocolSupport.Minimum Java version is 17.
When launching uLib for the first time (or if the respective caching folder was removed), it will download a few of dependencies/libraries.
