An example of custom rules' implementation for the two most popular static code analysis tools for Kotlin: Detekt and KtLint.

It demonstrates minimal required configuration for a custom rules' project, and comes with everything you need to build the rules and run them against the sample code. Including the Detekt and KtLint executables.

Detekt

To build custom rules for Detekt execute the following commands:

1. cd detekt-rules
2. ./gradlew clean build

Then run Detekt with custom rules enabled against the sample code:

java -jar ../detekt.jar -i ../Sample.kt --plugins ../detekt-rules/build/libs/detekt-custom-1.0.jar --config ../detekt.yml

NOTICE you need Java being referenced in your path variable.
