Rescan 240 jars of the 2.9.0-RC-2 instance and freeze the result as a new ABI baseline next to the +678 one. All baseline rows are still present and every scanned type and member resolves against the port. - 28 consumer jars: ThaumicEnergistics is new (Class.forName on TileMultipart for Waila providers) - GT5U now calls BlockMultipart.reduceMOP (Scala Tuple2) for ProjectRed wire recoloring; no Java replacement yet, recorded in the ledger - GuideNH 1.3.41 replaced its reflection with direct links - AE2 links JCuboidPart.bind from its host refresh fix - Source heads refreshed to 2026-10-16; only GT5U, ProjectRed and ProjectBlue changed FMP-referencing files - Add manual checks for GT5U spray cans and ThaumicEnergistics Waila
ForgeMultipart
An API for dynamically handling different functional parts in the one block space, for Minecraft 1.7.10 / Forge. This is the GT New Horizons fork.
Using the API
Depend on the dev artifact, for example com.github.GTNewHorizons:ForgeMultipart:<version>:dev, alongside GTNH
CodeChickenCore. Start at the Java API index: it lists the supported entry points with a guide and a
compiling Java example for each. You do not need Scala in your own mod to use them.
If you are rebuilding an existing integration against the Java port, read the release notes first. Already compiled consumer jars keep working.
Building
The codebase is being ported from Scala to Java. Most sources are Java now, but they still live under
src/main/scala so they can be joint-compiled with the Scala files that remain. Everything compiles for Java 8.
./gradlew build
Use gradlew.bat on Windows. The maintainer guide covers the build boundaries,
the Forge functional tests and the full verification sequence. Port status and remaining work are in the
migration status.
