java.lang.NullPointerException

My console keeps throwing a NullPointerException ever since I seperated my Commands into their own Classes. I'm doing it abstract through a CommandManager & everything works but for some reason the commands keep throwing a NullPointerException. I don't think it's my Plugin.yml either cause its structured accordingly as well.

CommandManager Class

Code:

package chuanyeow.Commands;

import java.util.ArrayList;

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class CommandManager implements CommandExecutor {
    private ArrayList<AbstractCommand> commands = new ArrayList<AbstractCommand>();

    public void setup() {
        commands.add(new forcestartCommand());
        commands.add(new hauntCommand());
        commands.add(new hubitemsCommand());
        commands.add(new manhuntlobbyCommand());
        commands.add(new menuCommand());
        commands.add(new serverhelpCommand());
        commands.add(new serverinfoCommand());
        commands.add(new spawnCommand());
    }

    @Override
    public boolean onCommand(CommandSender commandSender, Command command, String s, String[] strings) {
        Player player = (Player) commandSender;
        AbstractCommand target = get(command.getName());

        if (target == null) {
            System.out.println(target);
            return true;
        }
       
        try {
            target.onCommand(player, strings);
        } catch (Exception e) {
            System.out.println(e);
        }
        return true;
    }

    private AbstractCommand get(String name) {
        for (AbstractCommand cmd : commands) {
            if (cmd.name().equalsIgnoreCase(name)) {
                return cmd;
            }
        }
        return null;
    }
}

Abstract Command Class

Code:

package chuanyeow.Commands;

import org.bukkit.entity.Player;

public abstract class AbstractCommand {
    public abstract void onCommand(Player player, String[] args);

    public abstract String name();

    public abstract String info();
}

And in each Command Class is structured standard:
SpawnCommand Class

Code:

public class spawnCommand extends AbstractCommand {
    private Final plugin;

    // Commands
    @Override
    public void onCommand(Player player, String[] args) {
        player.message("Ooga Booga!");
        return;
    }
   
    @Override
    public String name() {
        return "spawn";
    }

    @Override
    public String info() {
        return "Spawns the Player into the Hub";
    }

The way I initialize it in the Final class is like so:

Code:

public void LoadCommands() {
        try {
            // Command Manager
            commandManager = new CommandManager();
            getCommandManager().setup();
            // Load Commands
            this.getCommand("forcestart").setExecutor(getCommandManager());
            this.getCommand("haunt").setExecutor(getCommandManager());
            this.getCommand("hubitems").setExecutor(getCommandManager());
            this.getCommand("manhuntlobby").setExecutor(getCommandManager());
            this.getCommand("menu").setExecutor(getCommandManager());
            this.getCommand("serverhelp").setExecutor(getCommandManager());
            this.getCommand("serverinfo").setExecutor(getCommandManager());
            this.getCommand("spawn").setExecutor(getCommandManager());
        } catch (Exception e) {
            System.out.println(e);
            return;
        }
        getServer().getConsoleSender().sendMessage(ChatColor.LIGHT_PURPLE + "Commands Completed!");
    }

I feel like the NullPointerException answer is staring me in the face but I really am stumped.

1. Please follow the Java naming conventions.
2. Can you post the stacktrace as well?
