Minecraft 26.3 port workspace
This is an experimental alpha port for issues #97–#104, not gameplay parity
with the Minecraft 1.21.1 release. It registers basic items and a runtime Age
prototype with persisted seeds. The operator-only rivencraft_port age
commands create and inspect separate vanilla-terrain levels. Descriptive Book
travel and named Linking Book binding/travel work as limited probes. Authored
generation, most content, recipes, workstations, portal systems, modifiers and
the destination preview renderer remain unported. Use a test world and keep a
backup; do not substitute this JAR for the 1.21.1 mod or import 1.21.1 saves.
From the repository root:
./gradlew -p ports/mc263 build
This standalone Gradle build uses Minecraft 26.3, NeoForge 26.3.0.99, ModDevGradle 2.0.148, and Java 25. The repository root remains the independent Minecraft 1.21.1/Java 21 build:
./gradlew build
The alpha JAR is under ports/mc263/build/libs. Continue the port and its
full dual-version validation in issues #98–#104 before calling 26.3 stable.
The dedicated development server uses build/run-server, with its own world
and properties. Set a nonconflicting server-port there before running if
another Minecraft server is active. The prototype restores all indexed Ages
during the Overworld load, before initial chunk preparation completes.
