Résolu Problème PluginMessage

[DuckInGame]

Bonjour / Bonsoir,
Je créer un plugin de Hub pour mon serveur et quand je tente de faire connecter un joueur sur un autre lobby, une erreur apparaît dans la console, je suis sous Spigot-1.8, je me suis renseigner sur le wiki des plugins message de spigot (https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/), hélas, j'ai rien trouvé par rapport à mon bug

Voici l'erreur se trouvant dans la console :

Et voici le code du plugin :

import com.google.common.io.ByteArrayDataOutput;
import com.google.common.io.ByteStreams;

import fr.DuckInGame.MainPluginHub.Main;

public class ClickInGameMenu implements Listener {
    
    private Main plugin = Main.getPlugin(Main.class);
    
    @EventHandler
    public void onClickInGameMenu(InventoryClickEvent e) {
        ItemStack is = e.getCurrentItem();
        Inventory inv = e.getInventory();
        Player p = (Player) e.getWhoClicked();
        int slot = e.getSlot();
        
        if(is == null) return;
        if(inv.getName().equalsIgnoreCase("Game Menu - Page 1")) {
            ByteArrayDataOutput out = ByteStreams.newDataOutput();
            Random random = new Random();
            if(slot == 9) {
                String[] hubservers = {"hub1", "hub2", "hub3"};
                
                out.writeUTF("Connect");
                out.writeUTF(hubservers[random.nextInt(hubservers.length)]);
                
                p.sendPluginMessage(plugin, "BungeeCord", out.toByteArray());
            }
        }
    }

}

Merci d'avance de votre aide,
Cordialement DuckInGame.

Bonjour,

// private Main plugin = Main.getPlugin(Main.class);
player.sendPluginMessage(plugin, "BungeeCord", out.toByteArray());

Il semblerait que ta variable plugin soit nulle, je ne sais pas comment tu définis Main#getPlugin(Class), mais à mon avis pas de la bonne manière.
Le plus simple est de faire une variable globale :

public class MyPlugin extends JavaPlugin {
    public static MyPlugin instance;
    
    @Override
    public void onEnable() {
        instance = this;
    }
}

player.sendPluginMessage(MyPlugin.instance, "BungeeCord", out.toByteArray());

Et sinon je vois que tu as des majuscules dans tes noms de packages, par convention ceux-ci doivent être en minuscules :

fr.duckingame.mainpluginhub.events.ClickInGameMenu

Cordialement,
ShE3py.
