Description of issue :

I am encountering a ClassNotFoundException error at startup or when loading plugin data (such as Multiverse-Inventories) on Mohist 1.20.1.

The error is caused by a failure to load a Spigot-specific inner class (BookMeta$Spigot) during the static initialization of the object metadata serialization class (ItemMeta). This issue suggests that the required inner class is missing or incorrectly referenced in the compiled Mohist JAR.

The class org.bukkit.inventory.meta.BookMeta$Spigot is an internal Spigot dependency required for CraftMetaBook initialization and is either not present or incorrectly mapped/shaded in the Mohist JAR compiled for 1.20.1.

Thanks in advance for fixing it, i know it could be long to fix ^^'
