rules_mc

Bazel rules to download Minecraft.

Features:

• Download Minecraft client & server JARs and mappings
• Download Minecraft client assets (both legacy and new style)
• Download Minecraft libraries from official repository
• Handle platform constraints and native library extracting

Usage

Insert following template into your MODULE.bazel:

bazel_dep(name="rules_mc", version="0.0.1")
archive_override(
module_name="rules_mc",
integrity="<Insert hash from releases>",
url="<Insert URL from releases>",
)

And declare Minecraft versions you want in MODULE.bazel:

minecraft=use_extension("@rules_mc//:extensions.bzl", "minecraft")
minecraft.version(
# Specify the game versionversion="1.21.8",
# Download client assetsassets=True,
# Download client/server JARs and mappingsclient=True,
client_mappings=True,
server=True,
server_mappings=True,
)
# You may need it to exclude libraries from downloading from Mojang.# For example, Fabric loader refuse to load when there are two ASM libraries on classpath (one comes from rules_mc, another comes from rules_jvm_external or something like it).minecraft.exclude_library(names= [
"org.ow2.asm:asm:9.6",
])
use_repo(minecraft, "minecraft")
use_repo(minecraft, "minecraft_assets")

Once you set up, refer Minecraft artifacts using these labels:

@minecraft//<version>:client
@minecraft//<version>:server
@minecraft//<version>:client_libraries
@minecraft//<version>:client_mappings
@minecraft//<version>:server_mappings
@minecraft_assets//:assets_<version>
# All assets, useful to being passed to client as runtime dependencies
@minecraft_assets//:assets
