Null pointer exception w pluginie

pokaż 16linijka Maina

Jest u samej góry nie ma numeracji ale jest to linia

ScoreboardManager manager = Bukkit.getScoreboardManager();
	Scoreboard board = manager.getNewScoreboard();

Zapomniałem dodać że jest to robione zgodnie z tym poradnikiem:

package pl.kangur88.dzikiepvp;

import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.entity.EntityDamageByEntityEvent;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.ScoreboardManager;

public class Main extends JavaPlugin{

	ScoreboardManager manager;
	Scoreboard board;
	
	@Override
	public void onEnable() {
		super.onEnable();
       manager = Bukkit.getScoreboardManager();
       board = manager.getNewScoreboard();
	}
	
	@Override
	public void onLoad() {
		super.onLoad();
		Objective objective = board.registerNewObjective("health", "health", "health");
		objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
		objective.setDisplayName("/ 20");
	}
	
	@EventHandler
	public void damage(EntityDamageByEntityEvent e) {
		for(Player online : Bukkit.getOnlinePlayers()){
			  online.setScoreboard(board);
			  online.setHealth(online.getHealth()); //Update their health
		}
	}
}
