Building from Source

The project uses Stonecutter to build every supported Minecraft version from a single source tree.

See the Stonecutter Development Guide for version switching, single-version builds, full release builds, client launch tasks, and troubleshooting.

# `build` delegates to the Stonecutter multi-version build and collects build/jars/
JAVA_HOME=<jdk-25> ./gradlew build

# Equivalent explicit task
JAVA_HOME=<jdk-25> ./gradlew buildAllJars

The release jars are collected into build/jars/ — one per version, e.g. opensoundboard-0.3.0+mc26.1.2.jar. (Each is also left in versions/<version>/build/libs/.)

To work on a single version, switch the active version first, then build or run just that node:

./gradlew stonecutterSwitchTo26.1.2   # pick the active version
./gradlew :26.1.2:build               # build just that node -> versions/26.1.2/build/libs/
./gradlew client_26_1_2               # switch + launch its client

Minecraft 26.x builds require the Gradle daemon to run on Java 25 (set JAVA_HOME accordingly); 1.21.x versions target Java 21 but build fine on a Java 25 daemon too. The root build task delegates to the isolated Stonecutter builds; use a fully qualified task such as :1.21.11:build when working on only the active version.
