FastAsyncWorldEdit (Fork with Minecraft 26.1 Support)

This is an unofficial fork of FastAsyncWorldEdit that adds support for Minecraft 26.1 (new versioning scheme).

What changed in this fork

New adapter for MC 26.1

• Created adapter-26_1 with full NMS support for Minecraft 26.1
• Ported all 26+ API changes: ChunkPos records, non-generic TicketType, removed moonrise/starlight APIs, new ServerLevel constructors, etc.
• Disabled reobfJar for 26.1 (Mojang no longer obfuscates server jars)

Patched paperweight-userdev

• Upstream paperweight 2.0.0-SNAPSHOT (commit 7d74656) added dev-bundle v8 support but dropped v7 backward compatibility
• Our paperweight fork re-adds DevBundleV7 dispatch so both old (1.21.x) and new (26.1+) adapters work

Build system adjustments

• Added mavenLocal() to pluginManagement and adapter repositories for local artifact resolution
• Updated worldedit-libs/build.gradle.kts for Gradle 9.4 compatibility with new paperweight
• Temporarily disabled adapters 1_21_4, 1_21_5, 1_21_6, 1_21_9, 1_21_11 (codebook/ASM incompatibility with JDK 25 or dev-bundle v7 issues)

Prerequisites

• JDK 25 (Oracle or Temurin)
• Git

Building

1. Build Paper 26.1

Your local Paper fork must be built first to publish the dev-bundle:

cd Paper
./gradlew publishToMavenLocal

This publishes io.papermc.paper:dev-bundle:26.1-R0.1-SNAPSHOT to ~/.m2/repository/.

2. Build paperweight from source

Clone and build the patched paperweight (with DevBundleV7 backward compatibility):

git clone https://github.com/roggy666/paperweight-26.1.git paperweight
cd paperweight
./gradlew publishToMavenLocal

This publishes io.papermc.paperweight:paperweight-userdev:2.0.0-SNAPSHOT to ~/.m2/repository/.

3. Build FAWE

cd FastAsyncWorldEdit
./gradlew build

Output jar:

worldedit-bukkit/build/libs/FastAsyncWorldEdit-Bukkit-2.15.1-SNAPSHOT.jar
