Anvil Recipes

I have an overall basic understanding of using an anvil with bukkit.

I want to make it so If I add two items you cant normally add together in an anvil, I get a custom result.
Heres what I got so far, very simple.

EventsClass.java (open) EventsClass.java (close)

Code:

package me.alton.Dust.Events;

import java.util.List;

import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.inventory.AnvilInventory;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.InventoryView;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;

import me.alton.Dust.Items;

public class EventsClass implements Listener{
    @EventHandler
    public void onInventoryClick(InventoryClickEvent e)
    {
        Inventory inv = e.getInventory();
        if (inv instanceof AnvilInventory)
        {
            AnvilInventory anvil = (AnvilInventory)inv;
            InventoryView view = e.getView();
            int rawSlot = e.getRawSlot();
         
            if (rawSlot == view.convertSlot(rawSlot))//If inv is upper inv (Anvil inv)
            {
                ItemStack[] items = anvil.getContents();
             
                ItemStack firstSlot = items[0];
                ItemStack secondSlot = items[1];
                if (secondSlot == Items.dust)
                {
                    Material resultMat = firstSlot.getType();
                    String resultName = firstSlot.getItemMeta().getDisplayName();
                    List<String> resultLore = secondSlot.getItemMeta().getLore();
                 
                    //creating result
                    ItemStack result = new ItemStack(resultMat);
                    ItemMeta resultMeta = result.getItemMeta();
                    resultMeta.setLore(resultLore);
                    result.getItemMeta().setDisplayName(resultName);
                    //creating result

                    anvil.setItem(2, result);
                }

            }
        }
    }
}

The problem is that my result slot when I have those two items there doesn't get set.
I've looked around and I saw that some people are saying its a problem with bukkit not fully implementing a set slot function for the result. But that dosnt make sense to me because theres got to be a way to do it.

 

Catch this
https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/inventory/PrepareAnvilEvent.html

And use SetResult.
