ForgeGradle vs Vineflower

ForgeGradle is a free Gradle plugin and Minecraft mod development framework used with Forge and FML. Its documentation focuses on setting up a mod development environment, not teaching Java, Groovy or Gradle. Setup requires a Java Development Kit and familiarity with an integrated development environment. The guide provides commands to generate run configurations for Eclipse, IntelliJ IDEA and Visual Studio Code. Configurations can specify arguments, working directories, task names, environment properties and system properties; Forge supplies client, server, data and gameTestServer run types. Developers can select human-readable mappings and use a reobf task to convert a mod JAR to SRG mappings for production. Dependencies can be sourced from repositories or a local flat directory and wrapped with fg.deobf. An optional Jar-in-Jar system bundles selected dependencies and records metadata during the build. The documentation covers Minecraft versions 1.12 through 1.19, plus 1.19.4. Its default stable and snapshot mappings are typically incomplete and are no longer available as of Minecraft 1.17. The repository identifies the license as LGPL-2.1.

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.
