Ran on Kiln's test stand (2026-11-04): ShulkerLayers did not start: java.lang.NoClassDefFoundError: net/minecraft/core/component/DataComponentType.

What it needs from Kiln

• Mixin
• net.minecraft.core.component.DataComponentType
• net.minecraft.core.component.DataComponentType.Builder
• net.minecraft.network.codec.ByteBufCodecs
• net.minecraft.util.ExtraCodecs
• net.minecraft.world.level.storage.loot.functions.CopyComponentsFunction
• net.minecraft.world.level.storage.loot.functions.CopyComponentsFunction.Builder
• net.minecraft.world.level.storage.loot.parameters.LootContextParams
• JsonSyntaxException.getMessage()
• BuiltInRegistries.DATA_COMPONENT_TYPE
• ItemStack.get()
• LootPool.Builder.apply()
• LootTable.Builder.modifyPools()

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3), Mixin (0.5)
