Error Prone: Google's Secret Weapon for Bug-Free Lines of Code
summary
Error Prone is a static-analysis tool from Google that runs inside the javac compiler and uses AST-based checks to find subtle Java bugs (like risky null usage) and suggest fixes, going beyond tools such as Checkstyle or SpotBugs. The talk covers quick integration and minimal configuration for Maven/Gradle builds, a live demo that fails compilation on subtle errors to show the detailed diagnostics, and how to write custom, project-specific Error Prone checks.
