Crafting recipe not working

Got this code in my onEnable event.
Shows no errors but when I put the recipe in it doesn't work.

Code:

        
        ItemStack isBackpack = new ItemStack(Material.LEATHER_CHESTPLATE, 1);
        isBackpack.getItemMeta().setDisplayName("Backpack");
        isBackpack.getItemMeta().addItemFlags(ItemFlag.HIDE_ATTRIBUTES);
        isBackpack.getItemMeta().getLore().add("Backpack");
        ShapedRecipe srBackpack = new ShapedRecipe(isBackpack);
        srBackpack.shape("LLL", "LCL", "LLL");
        srBackpack.setIngredient('L', Material.LEATHER);
        srBackpack.setIngredient('C', Material.CHEST);
       
        getServer().addRecipe(srBackpack);

 

How you handle the ItemMeta will not work. That's how you should do it instead:

Code:

ItemMeta meta = item.getItemMeta();
meta.setDisplayName("...");
meta.doSomeOtherStuff(1, 2, 3);
item.setItemMeta(meta);

Does your plugin even load? Use the command /plugins and look if it is in red

 

Of course it loads -.-

 

@SuperSaltyGamer Full code please.

plugin.yml

Code:

name: Realism
description: Realism
author: SuperSaltyGamer
version: 1.0.0
main: realism.Main

 

@SuperSaltyGamer You really need to fix that package.
https://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html

Remove that first getConfig.options blah it's not needed
Your code is also commented out.

 

I commented it out because i wanted the plugin to run, it was stopping there.

Just now noticed, that an nullPointerException while enabling Realism

Thi line seems to be the problem

imBackpack.getLore().add("Backpack");

What am I doing wrong?
