Setting up permissions

hey guys,
I am working on merging a bunch of my plugins together, and I decided to add permissions with it. Currently I am working on making it so you must have permission "MC123CraftExtras.IHArmor" (stands for "iron horse armor" to craft iron horse armor. I have tried multiple videos and other resources, but gotten nowhere. Do I need to add a permissions.java class? I know I also need to add something in the Main.java class, but don't know what.
Here is my code: Here is the part of the code I am working on:

Code (java):

package com.MC123isme1.MC123CraftExtras;

import org.bukkit.Material;
import org.bukkit.event.Listener;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.ShapedRecipe;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements Listener {

    public void onEnable(){
     
        final ShapedRecipe ihArmor = new ShapedRecipe(new ItemStack(Material.IRON_BARDING));
        ihArmor.shape("  H", "CCC", "L L");
        ihArmor.setIngredient('H', Material.IRON_HELMET);
        ihArmor.setIngredient('C', Material.IRON_CHESTPLATE);
        ihArmor.setIngredient('L', Material.IRON_LEGGINGS);
        getServer().addRecipe(ihArmor);
    }
}

Thank you guys in advance for all the help!

Lastly, I know that I am the only person that has started discussions in this topic, but is that bad?

I'm not exactly sure what you're doing here. Are you creating a Permissions plugin, checking whether a player has a permission node, creating a Permission object...?

If you're checking for a permission:

Code (text):

Player player = thisismyplayer;
if(player.hasPermission("MC123CraftExtras.IHArmor")) {
    // do something
}

It is the latter one, it allows crafting of Iron Horse Armor, but only if you have the permission. When I used your code, the issue I'm having is that it has a red underline (error) on "thisismyplayer" and says it cannot be resolved to a variable.
Here is what I have:

Code (text):

        Player player = thisismyplayer;
        if(player.hasPermission("MC123CraftExtras.IHArmor")) {
       
        final ShapedRecipe ihArmor = new ShapedRecipe(new ItemStack(Material.IRON_BARDING));
        ihArmor.shape("  H", "CCC", "L L");
        ihArmor.setIngredient('H', Material.IRON_HELMET);
        ihArmor.setIngredient('C', Material.IRON_CHESTPLATE);
        ihArmor.setIngredient('L', Material.IRON_LEGGINGS);
        getServer().addRecipe(ihArmor);
        }

EDIT: No errors appear in Eclipse, only in the console
You guys will hate me for this:
Got this while loading the plugin, it doesn't work at all, but still appears green in /pl.

Heres my Main.java:

Code (java):

package com.MC123isme1.MC123CraftExtras;

import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.ShapedRecipe;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements Listener {

    public void onEnable(){

   
        Player player = getServer().getPlayer(getName());
        if(player.hasPermission("MC123CraftExtras.HorseArmor.IHArmor")) {
   
        final ShapedRecipe ihArmor = new ShapedRecipe(new ItemStack(Material.IRON_BARDING));
        ihArmor.shape("  H", "CCC", "L L");
        ihArmor.setIngredient('H', Material.IRON_HELMET);
        ihArmor.setIngredient('C', Material.IRON_CHESTPLATE);
        ihArmor.setIngredient('L', Material.IRON_LEGGINGS);
        getServer().addRecipe(ihArmor);
        }

    }
}
 

And my plugin.yml:

Code (yaml):

name: 123CraftExtras
main: com.MC123isme1.MC123CraftExtras.Main
version: 1
author: 123isme1
permissions:
    MC123CraftExtras.HorseArmor:
      description: Allows crafting of horse armor
      children:
        MC123CraftExtras.HorseArmor.IHArmor:
          description: Craft Iron Horse armor

Oh...derp
Also I found a post by dinnerbone that might help for the future
