Old versions

Version 1

The previous iteration of manifest.json only ever contains few basic information about the package, such as header, modules, and dependencies, being very similar to version 2 without the modern features.

These manifest files are documented from multiple built-in resource packs, which are found in the game's directory:

  • [NBT Compound / JSON Object]: The root tag.
    • [Int] format_version: The syntax version used in the manifest file, version 1.
    • [NBT Compound / JSON Object] header: The pack's display information.
      • [String] description: A description of the pack. Can be text or a translation key.
      • [String] name: The name of the pack. Can be text or a translation key.
      • [String] uuid: A unique identifier for the pack. Must be of the form "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", where x in a hexadecimal number (0-9 or a-f).
      • [Int Array] version: An array consist of three integer numbers representing the current version of pack.
      • [Int Array] min_engine_version: An array consist of three integer numbers representing the minimum version of the game the pack can run on.
    • [NBT List / JSON Array] modules: Describes modules which are content types that the pack may contain.
      • [NBT Compound / JSON Object]: A module object in the list.
        • [String] description: An internal description of the module.
        • [String] type: The type of the module, can be: "resource" (resource pack), "data" (behavior pack), and "skin_pack".
        • [String] uuid: An identifier unique to the module. Must be of the form "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", where x in a hexadecimal number (0-9 or a-f).
        • [Int Array] version: An array consist of three integer numbers representing the version of the pack.
    • [NBT List / JSON Array] dependencies: Describes external dependencies that the pack requires.
      • [NBT Compound / JSON Object]: Describes a pack dependency.
        • [String] uuid: uuid of the pack dependency.
        • [String] name: The name of the pack. Can be text or a translation key.
        • [Int Array] version: An array consist of three integer numbers representing the version of the pack.

Version 0

The very first version of manifest.json, at the time was named pack_manifest.json, is used back in the v0.16.0 alpha versions. Its syntax is very different from version 1, containing the header object with different properties that would be renamed in the next iteration. Notably, modules and dependencies are contained inside the header object.

It is retroactively called version 0 in the Creator Documentation. Additionally, when the pack containing this manifest is loaded in later versions, it would get converted to version 1 with the new manifest.json, while the old pack_manifest.json would get backed up as pack_manifest.json.old.[4]

Version 0 resource packs are seperated into the client and server packs, both serve very similar purposes to the modern resource pack (client) and behavior pack (server).

These manifest files are documented from multiple built-in resource packs, which are found in the game's directory:

  • [NBT Compound / JSON Object]: The root tag.
    • [NBT Compound / JSON Object] header: The pack's display information.
      • [String] pack_id: A unique identifier for the pack. Must be of the form "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", where x in a hexadecimal number (0-9 or a-f).
      • [String] name: The name of the pack. Can be text or a translation key.
      • [Int Array] packs_version: An array consist of three integer numbers representing the current version of pack.
      • [String] description: A description of the pack. Can be text or a translation key.
      • [NBT List / JSON Array] modules: Describes modules which are content types that the pack may contain.
        • [NBT Compound / JSON Object]: A module object in the list.
          • [String] description: An internal description of the module.
          • [String] type: The type of the module, can be: "resource" (client) and "data" (server).
          • [String] uuid: An identifier unique to the module. Must be of the form "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", where x in a hexadecimal number (0-9 or a-f).
          • [String] version: A string formatted like X.Y.Z representing the version of the pack.
      • [NBT List / JSON Array] dependencies: Describes external dependencies that the pack requires.
        • [NBT Compound / JSON Object]: Describes a pack dependency.
          • [String] uuid: uuid of the pack dependency.
          • [String] name: The name of the pack. Can be text or a translation key.
          • [String] version: A string formatted like X.Y.Z representing the version of the pack.
