[1.21] - Unable to add tags to custom enchantments

[Adil Yilan]

This is the code for my enchantment tags provider for data generation:

public final class ModEnchantmentTagsProvider extends EnchantmentTagsProvider {

	public ModEnchantmentTagsProvider(PackOutput packOutput, CompletableFuture<Provider> lookupProvider) {
		super(packOutput, lookupProvider);
	}

	@Override
	protected void addTags(Provider provider) {

		tag(EnchantmentTags.ARMOR_EXCLUSIVE)
        	.add(ArmorEnchantments.FREEZING_PROTECTION)
        	.add(ArmorEnchantments.LIGHTNING_PROTECTION)
        	.add(ArmorEnchantments.MAGIC_PROTECTION)
        	.add(ArmorEnchantments.SONIC_PROTECTION);
		
		tag(ModEnchantmentTags.XP_GAIN_EXCLUSIVE)
			.add(Enchantments.MENDING)
			.add(ArmorEnchantments.EXPLORATION);
	}
	
    @Override
    public String getName()
    {
        return "Unique Magic Enchantment Tags";
    }
}

 

So what am I doing here is:

1) Adding my custom protection enchantments to be ARMOR_EXCLUSIVE so they don't clash with existing protection enchantments

2) Adding tag that makes my custom EXPLORATION enchantment to be exclusive with MENDING enchantment

This is then registered in ModDataGenerators:

dataGen.addProvider(event.includeServer(), new ModEnchantmentTagsProvider(packOutput, lookupProvider));

When datagen is run, I end up with this error:

Caused by: java.util.concurrent.CompletionException: java.lang.IllegalArgumentException: Couldn't define tag minecraft:exclusive_set/armor as it is missing following references: uniquemagic:freezing_protection,uniquemagic:lightning_protection,uniquemagic:magic_protection,uniquemagic:sonic_protection

Enchantments have been migrated to 1.21 and they work in game as they did in 1.20.6.

I also get enchantment JSON files in src/generated/resources so that is working well too.

However, I cannot make these tags to work no matter what I try.

Is there something that I am missing?
