First I would like to state for the record I am running Mac OS X El Capitan, on a MacBook Pro.
I'm looking for information on how to get the source for the 1.13.2 server jar. Also, I'm wondering how Spigot/Bukkit wraps over the Minecraft server jar, I'm fairly experienced with Java itself but deobfuscation is not my forte. Anyhow. I'm looking into creating my own pluginish API that functions similar to how Bukkit has in the past but with a new outlook. So if anybody can provide information on getting the deobfuscated source of the Minecraft server jar for 1.13.2 I would be very grateful.
