The class enum:

Code:

public enum Wands {
    NOVICE_WAND(new NoviceWand()),
    APPRENTDIST_WAND(new ApprendistWand());
    public Wand wand;
    private Wands(Wand wand){
        this.wand = wand;
    }
    public static Wands fromString(String str){
        switch (str) {
        case "Novice":
            return NOVICE_WAND;
        case "Apprendist":
            return APPRENTDIST_WAND;
        default:
            return null;
        }
    }
}

The NoviceWand class:

Code:

public class NoviceWand extends Wand{
    public NoviceWand(){
        super();
        this.prefix = "§5";
        this.lore = new LinkedList<String>(Arrays.asList(ChatColor.RED+"Bacchetta base indispensabile per iniziare a praticare magia"));
        this.wand = new ItemStack(Material.STICK);
        this.cost = 500;
        this.advableSpells = Arrays.asList(Spells.FIREBALL_SPELL,Spells.VORTEX_SPELL);
        this.name = "Bacchetta per novellini";
    }
}

And the calling line:

Code:

Wand wand = Wands.NOVICE_WAND.wand;

 

can we see the class where you got your onCommand method? AmbitiousMagicMAIN.java:108

 

Solved by restarting the server. Then i got another error and i fixed it.
