No perms msg override

Hi,
how can I force my plugin to display MY no perms message instead of the default one(I'm sorry, but you do not have permission to perform this command. Please contact the server admin...)

My main class:

Code:

package main;

import org.bukkit.ChatColor;
import org.bukkit.plugin.java.JavaPlugin;

import commands.FlyCommand;
import commands.GameModes;
import commands.HealCommands;
import commands.OverridedDefaultComannds;
import commands.SpyingCommands;
import events.JoinQuitEvent;

public class Main extends JavaPlugin {

    public static String infoPrefix = ChatColor.translateAlternateColorCodes('&', "&4&lInfo&r >> ");
    public static String errorPrefix = ChatColor.translateAlternateColorCodes('&', "&4&lError&r >> ");
    public static String noPermsPrefix = ChatColor.translateAlternateColorCodes('&', "&4&lPerms&r >> ");

    public static String insufficientArgs = "Not enough arguments!";
    public static String playerNotOnline = "This player is not online right now!";
    public static String noPerms = noPermsPrefix + "You dont have permission to do that!";
    public static String unknownCmd = errorPrefix + "Unknown command!";
    public static String unknownCmdCon = "Unknown command!";

    @Override
    public void onEnable() {
        System.out.println("Plugin enabled!");
        this.getCommand("healme").setExecutor(new HealCommands());
        this.getCommand("heal").setExecutor(new HealCommands());
        this.getCommand("survival").setExecutor(new GameModes());
        this.getCommand("spectator").setExecutor(new GameModes());
        this.getCommand("creative").setExecutor(new GameModes());
        this.getCommand("adventure").setExecutor(new GameModes());
        this.getCommand("fly").setExecutor(new FlyCommand());
        this.getCommand("vanish").setExecutor(new SpyingCommands());
        this.getCommand("kill").setExecutor(new OverridedDefaultComannds());
        this.getCommand("seed").setExecutor(new OverridedDefaultComannds());
        this.getCommand("gamemode").setExecutor(new OverridedDefaultComannds());
        this.getCommand("teleport").setExecutor(new OverridedDefaultComannds());

        this.getServer().getPluginManager().registerEvents(new JoinQuitEvent(), this);

    }

    @Override
    public void onDisable() {
        System.out.println("Plugin disabled!");
    }
}

My other class:

Code:

package commands;

public class HealCommands implements CommandExecutor {

    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (command.getName().equalsIgnoreCase("healme")) {
            if (sender instanceof Player) {
                Player player = (Player) sender;
                if (player.hasPermission("command.healme")) {
                    if (((Player) sender).getHealth() >= 20) {
                        player.sendMessage(Main.errorPrefix + "You are already fully healed!");
                    } else {
                        player.setHealth(20);
                        player.setFoodLevel(20);

                    }

            } else {
                sender.sendMessage("Only players can execute this command!");
            }
        }

        if (command.getName().equalsIgnoreCase("heal")) {
            if (sender instanceof Player) {

                    } catch (NumberFormatException event) {
                        sender.sendMessage("Please use real numbers!");
                    }
                }
            }
        }
        return true;
    }
}

I would be glad if I don't have to interfere with anything else than my plugin to fix this problem.

Thanks for help, and sorry for maybe dumb question.

 

Yes.

 

I know it isn't a vanilla command. I don't get the question, nothing is adding it cause I have no more plugins installed besides PEX to work with perms for now.
