FindBugs vs CodeNarc: What are the differences?
Developers describe FindBugs as "An open-source static code analyser". It detects possible bugs in Java programs. Potential errors are classified in four ranks: scariest, scary, troubling and of concern. This is a hint to the developer about their possible impact or severity. On the other hand, CodeNarc is detailed as "Analyzes Groovy code for defects". A flexible framework for rules, rule sets and custom rules means it's easy to configure it to fit into your project. Build tool, framework support, and report generation are all enterprise ready.
FindBugs and CodeNarc belong to "Code Review" category of the tech stack.
