Spigot Commands funktionieren nicht

[MittelEgo]

Hey,
ich habe vor kurzer Zeit angefangen Plugins zu programmieren und habe jetzt 3 Commands fertig. Jedoch funktioniert nur eins von drei. Bei den nicht funktionierenden Commands erscheint immer die Meldung "An internal error occurred while attempting to perform this command" im Chat und in der Console

[14:23:10 INFO]: MittelEgo issued server command: /countdown

Funktioniert leider nicht. Das Plugin wird zwar angezeigt,wenn ich /pl mache,aber diesmal passiert gar nichts,wenn ich versuche die Commands auszuführen. Keine Fehlermeldung :/
In der Console kommt am Anfang eine Fehlermeldung:

Und Eclipse zeigt in der Mainklasse einen Fehler:

Trotzdem danke!

 

[WlanGehtNicht]

getCommand("Countdown").setExecutor(new CountdownCommand(this))

So sollte es gehen

 

[MittelEgo]

Vielen Dank! Es hat geklappt!

Edit:
Hey,ich habe wieder ein Command,der nicht funktioniert:

        if(sender instanceof Player) {
            Player p =  (Player) sender;
            if(p.hasPermission("plugin.present")) {

                    i.setAmount(65);
                    i.setItemMeta(im);
               
                    inv.addItem(i);

Wäre wirklich nett,wenn du mir dabei auch helfen könntest ^^

 

[WlanGehtNicht]

Caused by: java.lang.IllegalArgumentException: Enchantment level is either too low or too high (given 56, bounds are 1 to 5)

Das Enchantment Level ist zu hoch.


Du siehst ja auch, dass in der Zeile 32 von der Klasse PresentCommand ein Fehler ist:

at de.mittelego.lernen.commands.PresentCommand.onCommand(PresentCommand.java:32) ~[?:?]

i.addEnchantment(Enchantment.DAMAGE_ALL, 56);

Damit sollte es klappen:

i.addEnchantment(Enchantment.DAMAGE_ALL, 5);

 

[MittelEgo]

Jo,vielen Dank! Hat am Anfang trotzdessen nicht geklappt,aber ich habe den zweiten Fehler gefunden. Ich habe anstatt Dirt,dann Schwerter genommen und hat geklappt.
