## What it is
SpotBugs is a static analysis tool that finds bugs in Java bytecode, serving as the community-maintained successor to the abandoned FindBugs project. It detects over 400 bug patterns and integrates with build tools and IDEs like Maven, Gradle, Eclipse, and IntelliJ IDEA.

## Use cases
- find bugs in java code with static analysis
- replace findbugs since it is abandoned
- run static code analysis in gradle build
- detect null pointer dereferences and bad practices in java
- scan java project for security vulnerabilities with find-sec-bugs
- integrate bug detection into maven or ant builds
- check java code quality in CI pipeline

## When to choose
- you maintain a Java or JVM-language codebase and want automated bug detection
- you need a maintained replacement for FindBugs
- you want static analysis integrated into Maven, Gradle, Ant, or your IDE
- you need extensible bug detectors via plugins like fb-contrib or find-sec-bugs

## When to avoid
- your project is not on the JVM (it analyzes Java bytecode only)
- you need dynamic analysis, runtime profiling, or test coverage rather than static checks
- you want a full SonarQube-style quality platform rather than a focused bug finder
