A versatile GitHub Action to streamline the publication of Minecraft projects.

Supports mods, plugins, resource packs, and more, across various platforms such as Modrinth, GitHub Releases, and CurseForge. Features automatic value resolution and minimal configuration requirements for effortless setup and use.

Most values are resolved automatically, so to publish your project, you only need a minimal amount of configuration.

jobs:
  build:
    # ...
    permissions:
      contents: write
    steps:
      - uses: Kir-Antipov/mc-publish@v3.3
        with:
          # Only include this section if you wish to publish
          # your assets on Modrinth.
          modrinth-id: AANobbMI
          modrinth-token: ${{ secrets.MODRINTH_TOKEN }}

          # Only include this section if you wish to publish
          # your assets on CurseForge.
          curseforge-id: 394468
          curseforge-token: ${{ secrets.CURSEFORGE_TOKEN }}

          # Only include this section if you wish to publish
          # your assets on GitHub.
          github-token: ${{ secrets.GITHUB_TOKEN }}

The following verbose example is for illustrative purposes only and is not recommended for regular use. mc-publish was designed to require minimal configuration, so there's no need for all of these settings.

Overly complex configurations with hardcoded values that could be resolved automatically not only complicate your workflow but can also introduce errors. For example, attempting to use github-discussion: Announcements in a repository that doesn't have a "Announcements" discussion category or discussions in general would lead to problems.

As a rule of thumb, if you don't see a clear reason to use an input, it's best not to include it.

      // ...
      "custom": {
        "mc-publish": {
          "modrinth": "AANobbMI"
        }
      }

Your Modrinth API token. It's required if you want to publish your assets to Modrinth.

modrinth-token: ${{ secrets.MODRINTH_TOKEN }}

Set to true to feature the version on Modrinth; false otherwise. Default value is:

modrinth-featured: true

Sets the behavior for unfeaturing older Modrinth versions. Default value is subset, if modrinth-featured is set to true; otherwise, none.

modrinth-unfeature-mode: version-intersection | loader-subset

Available presets:

• none - no Modrinth versions will be unfeatured.
• subset - only those Modrinth versions which are considered a subset of the new one (i.e., new release supports all of the version's mod loaders and game versions) will be unfeatured.
• intersection - only those Modrinth versions which intersects with the new one (i.e., support at least one of the mod loaders and one of the game versions supported by the new release) will be unfeatured.
• any - all Modrinth versions will be unfeatured.

If none of the given presets suits your needs, you can construct a new one from the following values via bitwise OR, like so - game-version-intersection | loaders-subset:

• game-version-subset
• game-version-intersection
• game-version-any
• version-subset
• version-intersection
• version-any

Fabric mods can be marked as Quilt-compatible like so:

• fabric.mod.json

  {
    // ...

  >=21w37a <1.18.2
  1.19

Controls the method used to filter game versions. Default value is:

game-version-filter: releases | min-major | min-minor

Available filters (note that they can be combined to achieve the desired outcome):

• none - no filter is applied.
• releases - only include release versions.
• betas - only include beta versions of the game.
• alphas - only include alpha versions of the game.
• snapshots - include both alpha and beta versions.
• any - include any version types (release, beta, or alpha).
• min-patch - include versions with the minimum patch number.
• max-patch - include versions with the maximum patch number.
• min-minor - include versions with the minimum minor number.
• max-minor - include versions with the maximum minor number.
• min-major - include versions with the minimum major number.
• max-major - include versions with the maximum major number.
• min - include the earliest versions in a range, considering major, minor, and patch values.
• max - include the lates versions in a range, considering major, minor, and patch values.

Example of work of each individual filter for >=1.17 <=1.18 version range:

An array of dependencies required by your project. By default, mc-publish will take them from your project's metadata file.

dependencies: |
  required-dependency(required)
  optional-dependency@0.1.0(optional)
  recommended-dependency@0.2.0(recommended)
  embedded-dependency@0.3.0(embedded)

  incompatible-dependency(incompatible)
  fabric@0.81.1+1.19.4(required){modrinth:P7dR8mSH}{curseforge:306612}#(ignore:github)

The format for dependencies can be described as follows: id@version(type){platform:alias}#(ignore:ignored-platform). Each component of this format, with the exception of the id, is optional.

Available dependency types:

• required - for dependencies required to run. Without them a game will crash.
• recommended - for dependencies not required to run. Without them a game will log a warning.
• optional - for dependencies not required to run. Can be used as a kind of metadata.
• embedded - for dependencies embedded into the mod. Can be used as a kind of metadata.
• conflicting - for mods whose together with yours cause some kind of bugs, etc. With them a game will log a warning.
• incompatible - for mods whose together with yours might cause a game crash. With them a game will crash.

Defines the maximum number of asset publishing attempts. Default value is:

retry-attempts: 2

Specifies the delay (in milliseconds) between asset publishing attempts. Default values is:

retry-delay: 10000

Controls how the action responds to errors during the mod publishing process. Default value is:

fail-mode: fail

Available values:

• fail - immediately sets the action status to failed and terminates its execution.
• warn - warns about errors. The action won't be terminated, nor its status will be set to failed.
• skip - warns about errors. The action won't be terminated, but its status will be set to failed after all specified targets have been processed.
