Java Annotation Processing (JSR 269) allows developers to extend the Java compiler. This repository gathers resources related to this API, including annotation processors that generate code, tools to aid in development, and best practices for implementation. It addresses the problem of repetitive code by automating generation tasks during compilation, leading to cleaner and more maintainable codebases.
This curated list provides a comprehensive overview of various annotation processors, covering diverse use cases from dependency injection to code generation and static analysis. It also includes tools for testing and developing annotation processors, and valuable learning materials like presentations and blog posts. The resource list is organized by functionality (annotation processors, tools, and learning materials), making it easy to find relevant options.
- avaje-inject: Compile-time dependency injection library using annotation processing for code generation.
- Google Auto: Collection of source code generators for Java using annotation processing.
- JUnit 5 Testing: Tools for testing annotation processors and compile-time checks.
- APTK: A toolbox for building annotation processors efficiently.
- Slideshows & Articles: Resources covering annotation processing concepts, practical applications, and testing techniques.
- Hickory: A framework for accessing annotation types and generating prisms for compile-time access.
