How to reduce players item from inventory

On server side, how to reduce players item from inventory?

 

I used below codes.

 

It doesn't work. Nothing changed.

@Override
	public IMessage onMessage(CostMessage message, MessageContext ctx) {
		EntityPlayerMP player = ctx.getServerHandler().player;
		if (message != null) {
			ItemStack stack = message.getItemStack();
			if (stack == null)
				return null;
			InventoryPlayer inv = player.inventory;
			inv.deleteStack(stack);
		}
		return null;
	}

 

It caused NoSuchMethodException with func_184429_b

@Override
	public IMessage onMessage(CostMessage message, MessageContext ctx) {
		EntityPlayerMP player = ctx.getServerHandler().player;
		if (message != null) {
			ItemStack stack = message.getItemStack();
			if (stack == null)
				return null;
			InventoryPlayer inv = player.inventory;
			int amount = stack.getCount();
			int p = 0, cnt = stack.getCount();
			while (cnt > 0) {
				int slot = inv.getSlotFor(stack);
				int cntFrom = inv.getStackInSlot(slot).getCount();
				cnt -= cntFrom;
				if (cnt > 0) {
					inv.setInventorySlotContents(slot, null);
				} else if (cnt != 0) {
					stack.setCount(-cnt);
					inv.setInventorySlotContents(slot, stack);
				}
			}
		}
		return null;
	}

 

Is there any method or way to reduce items from player's inventory by item name & count?
