java.lang.NoSuchMethodError "False positive"?

[American2050]

I was trying my mod on MultiMC and I got this error on console

 

java.lang.NoSuchMethodError: net.minecraft.item.Item$ToolMaterial.getMaxUses()

 

Then I go back to eclipse, try the mod and it launchs without errors, then I build it again, try it again on MultiMC and it does launch ok.

 

What could be happening?

 

The error came from this lines of code mainly:

 

private static final ToolMaterial STICK = EnumHelper.addToolMaterial("STICK", 0, 353, 2.0F, 0.0F, 15);

public static final Item fake_dongle = new FakeDongle(STICK, "fake_dongle");

 

And on FakeDongle

 

    public FakeDongle(ToolMaterial material, String name)
    {
//    	super(material);
        this.maxStackSize = 1;
        this.setMaxDamage(material.getMaxUses());
        this.setRegistryName(name);
	this.setUnlocalizedName(ModInfo.MODID.toLowerCase() + ":" + name);

    }

Yes it works now. If I remember correctly I think time ago something similar happened, also with this ToolMaterial thing.
