A glob of the secondary files to upload. Default value is build/libs/*-@(dev|sources).jar.

files-secondary: build/libs/*-@(dev|sources).jar

name: Sodium 0.3.2 for Minecraft 1.17.1

The version number. If no value is provided, a tag of the release that triggered the action is used.

version: mc1.17.1-0.3.2

loaders: |
  fabric
  forge

A list of supported Minecraft versions. If no value is provided, the minimum supported version will be retrieved from the configuration file of your mod, if any, otherwise it will be parsed from the version value (e.g., 0.40.0+1.17 results in 1.17), and then it will be expanded using the specified version-resolver.

game-versions: |
  1.16.5
  1.17
  1.17.1
  21w37a

Determines the way automatic game-versions resolvement works. Default value is releasesIfAny.

version-resolver: latest

Available values:

• exact - exact game version (1.16 -> 1.16)
• latest - the latest release of the given minor (1.16 -> 1.16.5)
• all - all versions of the given minor starting with the specified build (1.16.5 -> [20w45a, 20w46a, 20w48a, 20w49a, 20w51a, 1.16.5-rc1, 1.16.5])
• releases - all releases of the given minor starting with the specified build (1.16.3 -> [1.16.3, 1.16.4, 1.16.5])

A list of dependencies.

dependencies: |
  required-dependency | depends | *
  required-dependency | depends
  required-dependency
  optional-dependency | recommends | 0.1.0
  suggested-dependency | suggests | 0.2.0
  included-dependency | includes | 0.3.0
  conflicting-dependency | conflicts | *
  incompatible-dependency | breaks | *

As you can see, each dependency should be written on a new line using the following format - {id} | {kind=depends} | {version=*}.

Available dependency kinds:

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

Can be automatically retrieved from the config file of your mod:

• fabric.mod.json (Fabric)
