Architectury Loom vs Vineflower

Architectury Loom is a free Gradle plugin for setting up development environments for Minecraft mods. It supports Fabric, Forge, NeoForge, and Quilt, and is described as a ForgeGradle replacement based on FabricMC Loom. Developers can choose Yarn, Official Mojang Mappings, or MCP mappings. Loom uses Fernflower and CFR to generate source code with comments. The documented IDE support is IntelliJ IDEA and Visual Studio Code; other IDEs are not tested or supported. The project requires Gradle 8.1 or newer and runs on Linux, macOS, and Windows. Its documentation labels the project experimental and says issues may arise, with reports directed to the issue tracker. The repository uses the MIT license, and community discussion is available through Discord. The latest listed release is 1.17, which includes an API for converting access wideners to access transformers for Forge and NeoForge.

Vineflower is a free, open-source Java decompiler for producing readable code from Java classes. It supports modern Java, including J21 and later, with automatic reformatting and multithreaded decompilation. The main distribution is a JAR from GitHub releases and Maven Central. You can run that JAR from the command line with archives or files, saving output to an archive or folder or printing it to the console. Vineflower can also be added through Maven or Gradle, and an IntelliJ plugin is available. A command-line option can emit Kotlin classes as Kotlin; the full distribution includes an experimental Kotlin decompiler plugin and other plugins for IntelliJ IDEA annotations and variable renaming. A slim artifact omits built-in plugins. Running requires a Java 17 or newer JVM. An experimental plugin system supports output changes or new JVM languages. The project calls itself a work in progress and welcomes contributions. It is licensed under Apache-2.0.
