====== architectury.common.json ====== architectury.common.json is a mod metadata format for common modules of cross-platform mods. These files can be placed at the top level of mod sources to provide some features -- interface injection and access wideners -- in development environments. ===== Structure ===== See more details about the individual features in the sections below. * ''accessWidener'': path to an access widener file * ''injected_interfaces'': a map of injected interfaces (all type names in Intermediary mappings and JVM internal format) * //type name//: an array of interface names injected to the type named in the key ===== Interface injection ===== Compile-time interface injection is available in Architectury common modules by adding an ''injected_interfaces'' object to the architectury.common.json. The keys are the Minecraft class names in Intermediary mappings, and the values are the interfaces to inject as arrays. { "injected_interfaces": { "net/minecraft/class_1234": ["com/example/MyInterface"] } } All type names should be provided as JVM internal names (e.g. ''com/example/Outer$Inner'' instead of ''com.example.Outer.Inner''). For more information, see the [[https://fabricmc.net/wiki/tutorial:interface_injection|Fabric Wiki page about interface injection]]. ===== Access wideners ===== An access widener file can be specified with the ''accessWidener'' key: { "accessWidener": "my_mod.accesswidener" } This is mainly useful for libraries that declare transitive access wideners, i.e. AWs that apply to projects that depend on the library. Access wideners should be written in your project's mappings (e.g. Yarn or Mojang mappings) as with Fabric projects. Further details on the access widener format can be found on the [[https://fabricmc.net/wiki/tutorial:accesswideners|Fabric Wiki page about access wideners]].
