Development Assistance Plugin won't do anything

I made this plugin and I finally got it to load on the server, but the scoreboard won't show up. It is showing on my server. Please help.

Scoreboard Builder class

Code:

package com.scoreboard.main;

import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.ScoreboardManager;


public class ScoreboardBuilder {

        private ScoreboardManager sbManager;
        private Scoreboard scoreboard;
        private Objective objective;
       
        public ScoreboardBuilder(String title) {
            sbManager = Bukkit.getScoreboardManager();
            scoreboard = sbManager.getNewScoreboard();
            objective = scoreboard.registerNewObjective("server", "dummy");
            objective.setDisplayName(title);
            objective.setDisplaySlot(DisplaySlot.SIDEBAR);
        }
       
        public void add(String info, int index) {
            getObjective().getScore(info).setScore(index);
        }
       
        public void send(Player... players) {
            for(Player player : players) {
                player.setScoreboard(getScoreboard());
            }
        }

        public ScoreboardManager getSbManager() {
            return sbManager;
        }
       
        public Scoreboard getScoreboard() {
            return scoreboard;
        }
       
        public Objective getObjective() {
            return objective;
        }
}

OnJoin class:

Code:

package com.scoreboard.listeners;

import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;

import com.earth2me.essentials.api.Economy;
import com.earth2me.essentials.api.UserDoesNotExistException;
import com.massivecraft.factions.FPlayer;
import com.massivecraft.factions.FPlayers;
import com.scoreboard.main.Main;
import com.scoreboard.main.ScoreboardBuilder;

public class OnJoin implements Listener {

    private int money;
    private String money_str = String.valueOf(money);
    private FPlayer fPlayer;
    private OnGroupManager groupManager = Main.getInstance().getGroup();
   
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent event) {
        Player player = event.getPlayer();
        Main.getInstance().getLogger().info("here");
        fPlayer = FPlayers.i.get(player);
        updateMoney(player);
    }
   
    private void buildScoreboard(Player player) {
        ScoreboardBuilder scoreboard = new ScoreboardBuilder("§4Dismantle§cPvP");
        scoreboard.add("§eIGN:", 14);
        scoreboard.add("§c" + player.getName(), 13);
        scoreboard.add("   ", 12);
        scoreboard.add("§eRank:", 10);
        scoreboard.add("§c" + groupManager.getGroup(player), 9);
        scoreboard.add("         ", 8);
        scoreboard.add("§eBalance:", 7);
        scoreboard.add("§c" + money_str, 6);
        scoreboard.add(" ", 5);
        scoreboard.add("§eFaction Name:", 4);
        scoreboard.add("§c" + fPlayer.getFaction().getTag(), 3);
        scoreboard.add("  ", 2);
        scoreboard.add("§eYour Power:", 1);
        scoreboard.add("§c" + String.valueOf(Math.floor(fPlayer.getPower())), 0);
        scoreboard.send(player);
    }
   
    private void updateMoney(final Player player) {
        Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(Main.getInstance(), new Runnable() {
            public void run() {
                try {
                    money = Economy.getMoneyExact(player.getName()).intValue();
                    money_str = String.valueOf(money);
                    buildScoreboard(player);
                } catch (UserDoesNotExistException e) {
                    e.printStackTrace();
                }
            }
        }, 0, 4 * 20);
    }
   
}

 

Do you have a plugin.yml? You don't wanna know how much trouble I've been in because there was no plugin.yml xD
