Java Compiler Plugins provide a powerful way to extend and customize the compilation process, enabling advanced code analysis, validation, and transformations. This talk explores the architecture of Java Compiler Plugins, their integration with the Java Compiler (javac), and practical use cases where they enhance code quality, enforce coding standards, or introduce additional functionality. Key aspects of creating custom plugins, potential challenges, and real-world examples are presented to demonstrate their capabilities. Modifying compiler behavior through Java Compiler Plugins proves extremely beneficial when dealing with legacy code, as it facilitates automated code improvements, ensures compliance with modern standards, and reduces technical debt.
