Hallo ihr,
ich habe ein kleines Problem, ich habe für meine Mod jetzt einen Installer geschrieben, da mich mehrere drum gebeten haben, alles funktioniert einwandfrei, nur wenn ich versuche die Datei in einen Ordner zu kopieren kriege ich folgende Meldung:
Bei folgendem Code:
Main.java
CopyFile.java
Und mein Debugmode sagt:
Alles bezieht sich auf:
In diesen Ordner soll die minecraft.jar reinkopiert werden.
Wie kann ich das Problem lösen? Ich habe mich schon stundenlang durchgegooglet aber nichts gefunden 🙁
