IntelliJ IDEA vs Ravel Remapper

IntelliJ IDEA is an IDE for professional Java and Kotlin development, available on Windows, macOS, and Linux. It offers context-aware completion, static analysis, and automated refactoring. The JVM debugger includes breakpoints, variable inspection, expression evaluation, and step-by-step execution. Gradle and Maven integrations cover building, packaging, testing, and deployment, while version-control support includes Git, Mercurial, Perforce, and Subversion. Users can process GitHub pull requests in the IDE, and plugins from JetBrains Marketplace add support for other languages, frameworks, and technologies. Core Java and Kotlin functionality remains free after the included 30-day Ultimate trial ends. The Ultimate subscription adds advanced tools and integrations and costs $100.00 for the first year, $199.00 for the second year, and $159.00 per year from the third year onward. Listed minimum hardware is a 4-core x86_64 or arm64 CPU, 8 GB total RAM, and 10 GB of disk space. Users can choose in IDE settings whether to share anonymous usage data.

Ravel Remapper is a free, MIT-licensed IntelliJ IDEA plugin for remapping Java and Kotlin source files. Built on IntelliJ’s Program Structure Interface and Mapping-IO, it supports Mixins, Class Tweakers, and Access Wideners; MixinExtras Expression is not supported. Developers can migrate mappings between Yarn and Mojang mappings, as described in Fabric documentation. From the editor’s Refactor menu, users choose mapping files, source and destination namespaces, and modules, then run the remap. Mapping files may be added manually or downloaded in the dialog, and users can select individual modules or all modules. The project recommends committing changes first, then searching for TODO(Ravel) and fixing detected issues manually. Installation is available through JetBrains Marketplace or a ZIP from GitHub Releases. It runs on Linux, macOS, and Windows; the latest listed release is version 0.6.4.
