OpenRewrite is an automated refactoring framework that helps developers modernise applications, migrate frameworks and maintain consistent source code. It uses reusable transformation rules, known as recipes, to make systematic changes across a codebase.
Unlike conventional text replacement tools, OpenRewrite uses a structured representation of source code that retains formatting and semantic information. This allows transformations to account for program structure and types while minimising unrelated changes to the original files.
Developers can apply existing recipes or create their own to automate repetitive maintenance tasks. Common uses include updating framework APIs, improving coding conventions and modifying dependency configurations.
This is free and open source software.
Key Features
- Automates source code refactoring using reusable, configurable transformation recipes.
- Uses Lossless Semantic Trees to retain formatting, comments and source code structure during transformations.
- Provides type-aware analysis and transformations for Java source code.
- Supports Kotlin and Groovy through established language modules.
- Processes structured configuration formats including XML, YAML, JSON, TOML, HCL and properties files.
- Offers recipes for migrating applications between framework and library APIs.
- Supports automated updates to dependencies and build configurations.
- Provides code transformations for improving style consistency and replacing deprecated APIs.
- Allows multiple recipes to be combined into larger refactoring operations.
- Supports declarative recipes defined using YAML.
- Provides APIs for developing custom transformations and analysis rules.
- Includes Maven and Gradle plugins for running recipes within existing development workflows.
- Preserves unrelated source formatting when applying supported structural transformations.
- Supports repeatable execution of transformations for maintaining consistent code across projects.
