Adil Yilan Posted June 15 Share Posted June 15 (edited) 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?
