Hey Leute, ich helfe gerade einem Server beim Aufbau mit ein paar Plugins.
Ich habe gestern ein Random TP Plugin geschrieben was auf meinem Test Server funktioniert aber auf dem richtigen Server nicht. Unten habe ich den Source Code und die Fehlermeldung. Kann mir wer helfen?

this.getCommand("wartung").setExecutor((CommandExecutor) new Main());
this.getCommand("tpr").setExecutor((CommandExecutor) new Main());
this.getCommand("randomperm").setExecutor((CommandExecutor) new Main());

Es liegt an den 3 Zeilen: "new Main()" ist eine ganz schlechte Idee.
