    So i'm using this Lib, https://bukkit.org/threads/npclib-create-fake-players-1-8-1-7-10-1-7-9.340234/

    It's to make custom npc's

    But I get an error on this line when spawning one:
    Code:
    NPCRegistry registry = NPCLib.getNPCRegistry("TacoRegistry", Bukkit.getServer().getPluginManager().getPlugin("npc"));
    Full class code:

    Code:
    import net.techcable.npclib.NPC;
import net.techcable.npclib.NPCLib;
import net.techcable.npclib.NPCRegistry;

import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.EntityType;

public class NPCSpawn implements CommandExecutor{
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(cmd.getName().equalsIgnoreCase("npc")) {
            NPCRegistry registry = NPCLib.getNPCRegistry("TacoRegistry", Bukkit.getServer().getPluginManager().getPlugin("npc"));
            NPC npc = registry. createNPC(EntityType.PLAYER, "TacoMan");
            npc.setProtected(true);
            npc.setSkin("Techcable");
            npc.spawn(Bukkit.getWorld("world").getSpawnLocation());
        }
        return true;
       
    }
}
    Stack trace:

    Code:

    You either need to include the classes on the server in the form of a plugin or you need to shade the files into your own jar.

    ...considering it's for the shade plugin, it goes under executions>execution>configuration, not in the scope of the whole project
