为什么我得到 "Unidentified mapping from registry minecraft:block"？

Question

我正在学习如何编写 Minecraft 模组（版本 1.14.4）并且能够制作物品。现在我正在尝试制作一个块。我正在关注实际上涵盖 1.14.3 的 this tutorial video，但我认为它已经足够接近了。

我目前收到此错误：

[20Mar2020 14:09:10.522] [服务器 thread/INFO] [net.minecraftforge.registries.ForgeRegistry/REGISTRIES]：注册表块：从世界中找到一个丢失的 ID examplemod:examplemod [20Mar2020 14:09:10.613] [服务器 thread/ERROR] [net.minecraftforge.registries.GameData/REGISTRIES]：来自注册表的未识别映射 minecraft:block examplemod:examplemod: 676

我在运行时也看到了这个：

我试过弄乱我如何命名注册表，但我似乎无法确定问题所在。也许我没有正确格式化我的 json 文件？

请注意，ItemList 和 BlockList 只是类，其中包含我创建的每个 Block/Item 的静态实例。

ExampleMod.java:

        blockRegistryEvent.getRegistry().registerAll(BlockList.mystery_block);

        LOGGER.info("Blocks registered.");
    }
}

}

blockstates/mystery_block.json:

{ "variants"：{ “”：{ "model": "examplemod:block/mystery_block" } } }

models/block/mystery_block.json:

{ "parent": "block/cube_all", "textures"：{ "all": "examplemod:block/mystery_block" } }

models/item/mystery_block.json:

{ "parent": "examplemod:block/mystery_block" }

这意味着在某个时候你有一个块注册为 "examplemod:examplemod"，而现在你没有。您可以安全地忽略该消息。如果您开始一个新世界而不是打开一个旧世界，您将不会收到该消息。

顺便说一句，不推荐使用 HarryTalks 学习 mod（在 Minecraft Forge forums 上）。显然他使用了几种不良做法（我实际上没有使用过）。备选建议是 Cadiboo's example mod, or McJty's tutorials.
