I would like to know if there is an existing way to open a working anvil. I tried p.openInventory(Bukkit.createInventory(null, InventoryType.ANVIL)) but the anvil doesn't work. I can't even get clicked items with InventoryClickEvent, or set items with p.getOpenInventory().getTopInventory().setItem(0, new ItemStack(Material.GUNPOWDER)).

It works with NMS but it makes cross-version management harder. I hope there is (or will be ) a proper way.

I saw that it was possible to open working workbenchs or enchant tables with p.openWorkbench and p.openEnchanting. Could it be possible to do the same for anvils ?
