ForgeFlower
What ForgeFlower is
ForgeFlower is a software project containing MinecraftForge’s modifications to FernFlower, intended to address bugs and inconsistencies in that decompiler. Its public repository identifies MinecraftForge/FernFlower as the main repository and links to FernFlower, which describes itself as an unofficial mirror of the Java decompiler. ForgeFlower’s repository includes source code, Gradle build files, a Gradle wrapper, and a FernFlower submodule. It is licensed under Apache License 2.0 and is available free.
FernFlower’s documentation describes command-line decompilation for class, zip, and jar files, as well as recursive directory scanning. It also lists options for inner classes, recovering names from debug information, and renaming ambiguous identifiers, including a custom renaming interface. These are FernFlower capabilities; ForgeFlower’s stated role is to modify that project. The linked documentation says the decompiler remains under development and that some command-line options target professional reverse engineers. ForgeFlower’s repository shows no listed releases or packages.
