Static Code Analysis For Kotlin
summary
Detekt is a static analysis tool for Kotlin that plugs into Gradle and uses a YAML config to enable rule sets, thresholds and reports; it runs locally via a git pre-commit hook or on CI and can fail builds when issues exceed a max. Under the hood it builds a PSI tree from the Kotlin compiler and traverses it with a KT tree visitor to implement rules like unsafe call nullable and use data class, plus examples: a data-class-no-methods rule and a too-many-functions threshold (default 11).
