@MrMobiLp
You have to use PrepareItemCraftEvent. Get the ingredient, and if that ingredient has a name, and if that name is equal to the name you want, then continue. If not, set the result to air (or null)

 

You need the name of the item (not the material). You can get it using itemstack.getItemMeta().getDisplayName();

 

Use if(ItemStack.getItemMeta().getDisplayName().Equals(your string here){
//Do something
}

 

check if it has display name first before, getting it, or you'll get a NPE

Code:

private String example = ChatColor.RED + "hey";
if (!itemStack.getItemMeta().hasDisplayname() || !itemStack.getItemMeta().getDisplayName().equals(example)) {
     return;
}
//item has displayname and its displayname is ChatColor.RED + hey
