Build from source

Use the included Gradle wrapper. The toolchain resolver can download the required JDK when needed.

./gradlew :1.21.1-fabric:buildAndCollect \
  :1.21.1-neoforge:buildAndCollect

The JARs and source JARs are written to:

build/libs/<mod-version>/

To run a development client, use one of these commands:

./gradlew :1.21.1-fabric:runClient
./gradlew :1.21.1-neoforge:runClient
