Runtime & Dependencies

JDK 17 or higher (OpenJDK / GraalVM)

Architecture

x86_64, ARM64 (Apple Silicon & Graviton)

🧠 How It Works

rewrite coordinates its core functionality through a modular Java pipeline. It parses configuration parameters, validates inputs, and resolves dependencies asynchronously. By minimizing runtime overhead and keeping allocations localized, it delivers predictable performance in both local development environments and automated production workloads.

🎯 Production Use Cases

Command-Line Automation

Execute automated build, deployment, and maintenance tasks directly from the terminal.

CI/CD Workflow Integration

Run non-interactive validation checks in GitHub Actions, GitLab CI, or local pre-commit hooks.

Developer Environment Setup

Standardize local engineering workstations with single-binary utility commands.

Scripting & Pipeline Orchestration

Chain complex multi-stage scripts with reliable error reporting and exits.

🚀 Getting Started

1

Install rewrite using your package manager: `git clone https://github.com/openrewrite/rewrite.git`

2

Initialize your project workspace or configuration file for rewrite.

3

Import rewrite into your codebase or invoke it directly from your terminal.

4

Execute your test suite or run `rewrite --help` to verify successful setup.

👍 Strengths

Active community backing with 3,750 GitHub stars and verified adoption.
Permissive open-source distribution under the Apache-2.0 license.
Built in Java for high execution speed and developer familiarity.
Cross-platform compatibility across modern Linux, macOS, and Windows environments.
Clean modular design allowing flexible configuration and pipeline integration.

⚠️ Considerations

Requires familiarity with Java and modern CLI workflows.
Ecosystem extensions may require manual configuration depending on environment constraints.
Active development roadmap means breaking API changes may occur across major versions.
