Save NBTTag UUIDLeast and UUIDMost only when crafting an item

This is my onEnable with "CustomRecipe.customrecipes();" (this class is below) that load all the recipes when the plugin load. Is there a way to add NBTTag UUIDLeast and UUIDMost for attributes modifies in a yml file only when a player craft a recipe? I know that one of them (or both) are stored in the crafted item that gives to it a specific characteristic to an item (like base damage or armor point).
Why when I check if the item type for "armor" attribute is a gold piece of armor it gives me:

Code:

org.bukkit.plugin.AuthorNagException: No legacy enum constant for GOLDEN_HELMET. Did you forget to define api-version: 1.13 in your plugin.yml?

(with all the pieces). Same for ITEM_SKULL or any skull

Code:

@Override
public void onEnable() {
    new UUIDDatabaseFile(this);
    RecipesFile.createRecipeFile();
    CustomRecipe.customrecipes();
    RegisterEvents();
    instance = this;
}

It looks like you are getting an error because the names of the items in minecraft are not always equal to the names of the bukkit enum constants in Material.
If you would like other people to help you, it would be very helpful to tell us the line number the exception mentioned and to show the line numbers of your java file.
