Version branches
Metadata published per Minecraft version branch.
mcmetaMinecraft metadata service
Versioned data with a hosted viewer in the docs.

Web viewer
The web viewer is hosted inside the docs and reads the same versioned mcmeta branches that power the data feeds. Use it to browse release and snapshot streams, inspect download metadata, and copy version details into build or CI notes.
What you can do inside the viewer:
- Scan release metadata (release date, protocol/data/pack formats).
- Open download links for version json, client/server jars, and mappings.
- See extra metadata when it exists (for example Yarn mapping versions or Purpur build numbers).
Gradle plugin
The Gradle plugin mirrors mcmeta version data into Gradle properties so build logic can pin Minecraft versions without hard-coding them. It also exposes an extras map for optional metadata such as Yarn mapping versions or Purpur build numbers, keeping multi-loader and CI builds consistent with the mcmeta branches.
When offline, the Gradle plugin can fall back to local mcmeta harvest backups stored in tools/mcmeta-harvest-backup. If an exact Minecraft version is not available, it will use the newest backup that shares the same major.minor and log a warning. If that still fails, it uses the newest available backup.
For NeoForge loader projects that already apply ModDevGradle, the plugin wires run tasks (client/server/data) using the requested Minecraft version.
