Quilt Mappings is a set of open, accurate, and easy-to-understand Minecraft mappings under the Creative Commons Zero license. Quilt Mappings seeks to provide the best of both worlds in terms of mapping quality: the accuracy and completeness of Mojang's official mappings, and the simplicity and set-in-stone conventions of its basis, the Yarn project.
Quilt Mappings exists to provide a stable set of mappings for everyone to contribute and improve upon. We provide mappings for all versions of Minecraft from 1.17 onwards. To see what version is currently being targeted for updates, check the current Git branch's name.
To use Quilt Mappings in your mod, you can use either quilt-loom
for Quilt mods or use our Intermediary publication on Fabric's loom
for Fabric mods. We recommend cloning the Quilt Template Mod
to start a new mod with QM, and you can also add this block to your build.gradle inside the dependencies block:
mappings("org.quiltmc:quilt-mappings:[version]:intermediary-v2")Note that on fabric-loom, you'll have to add the following to your repositories block as well, to tell gradle
where to find the QM publication:
maven { url = "https://maven.quiltmc.org/repository/release/" }QM versions are named after the Minecraft version they target, followed by +build.x,
with x being a number that increments with each new build of QM for that Minecraft version.
For example, 1.18.2+build.1 is the first build of QM for Minecraft 1.18.2. You can see additional
information and see what the latest QM build for each Minecraft version is with the quilt import tool.
(For automatic queries, try the versions API.)
When contributing names, the primary goal you should keep in mind is their intuitiveness: if you read this name with no context other than its declaration, would you know what it does? If not, the name either needs to be rethought or given javadocs if a good name can't be found.
We recommend coming up with original names as often as possible. In the case that something is too difficult to understand or name, check Mojang and Yarn's mappings for inspiration! Always spend some time thinking of original names before you make the decision to match theirs. For original names, it's best to check Mojang and Yarn anyway to make sure your name is correct - it's easy to make mistakes!

QM has a set of helpful Gradle tasks to make mapping easier, including:
Setup, download, and launch the latest version of Enigma automatically configured to use the merged jar and the mappings.
Compared to launching Enigma externally, the gradle task adds a name guesser plugin that automatically maps enums and a few constant field names.
Same as above, but unpicks the constants and launches Enigma with them. Can be a little bit slower to get going.
Build a GZip'd archive containing a tiny mapping between official (obfuscated), hashed-mojmap, and Quilt Mappings names ("named") and packages enigma mappings into a zip archive.
Builds a deobfuscated jar with Quilt mappings and automapped fields (enums, etc.). Unmapped names will be filled with hashed-mojmap names.
Decompile the mapped source code. Note: This is not designed to be recompiled.
Downloads the client and server Minecraft jars for the current Minecraft version to .gradle/minecraft
Merges the client and server jars into one merged jar, located at VERSION-merged.jar in the project directory
where VERSION is the current Minecraft version.
