Adding permission to item recipe?

So this is what im looking at right now, how would i add a permission to the recipe?

Code:java

public class CraftableHorseArmor extends JavaPlugin{
 
    public void onEnable(){
    Server server = this.getServer();
 
    ShapedRecipe iha = new ShapedRecipe(new ItemStack(417));
    iha.shape("  I","IBI","III");
    iha.setIngredient('I', Material.IRON_INGOT);
    iha.setIngredient('B', Material.WOOL, 15);
 
    ShapedRecipe gha = new ShapedRecipe(new ItemStack(418));
    gha.shape("  I","IBI","III");
    gha.setIngredient('I', Material.GOLD_INGOT);
    gha.setIngredient('B', Material.WOOL, 14);
 
    ShapedRecipe dha = new ShapedRecipe(new ItemStack(419));
    dha.shape("  I","IBI","III");
    dha.setIngredient('I', Material.DIAMOND);
    dha.setIngredient('B', Material.WOOL, 11);
 
    ShapedRecipe saddle = new ShapedRecipe(new ItemStack(329));
    saddle.shape("III","IBI");
    saddle.setIngredient('I', Material.LEATHER);
    saddle.setIngredient('B', Material.IRON_INGOT);
 
    server.addRecipe(iha);
    server.addRecipe(gha);
    server.addRecipe(dha);
    server.addRecipe(saddle);
    }
}
 

 

You have to check for the recipe being crafted in PrepareItemCraftEvent

 

Having permissions for certain recipes can be pretty tricky, I use this to do it myself
