Broadcast Message problem

It doesn't make a Broadcast Message!

MainClass:

Code:

package nick.plugin.de;

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

public class MainKlasse extends JavaPlugin{
  
    String pluginName = "Plugin";
    String prefix = "§7[§6" + pluginName + "§7] ";
  
    @Override
    public void onEnable() {
        Bukkit.getServer().broadcastMessage(prefix + "§9Das Plugin wurde geladen");
        //Also tryed it with: Bukkit.broadcastMessage(prefix + "§9Das Plugin wurde geladen");
    }
}

plugin.yml:

Code:

name: Plugin
version: 1.0
main: nick.plugin.de.MainKlasse
description: It is a plugin
author: Nick

Lemme guess, you reloaded the server while you were on it? This broadcast only broadcasts when the server starts to players.
Please note: Bukkit already shows you when the plugin is being loaded/unloaded.
