Lint

app.enableLintRules

The suite's own ktlint rules run on top of the standard ones once you turn them on in gradle.properties.

app.enableLintRules=true

Features

Spotless reads the property in every module it formats. It reads the plugin's own version from its jar and adds the matching lint-rules artifact as a custom rule set.

The versions can't drift apart. We build the coordinate from the plugin's own version, so moving the plugin version in your catalog moves the rules with it.

Rules

The rules cover conventions the type system can't enforce. Navigation is only constructed inside the modules that own it. Bindings come from the code generation annotations, not from code written by hand. A test is named after the behaviour it checks. Rules with exemptions read them from .editorconfig. So a module that legitimately breaks a rule says so in the file it applies to.

Every rule, and the .editorconfig property that exempts a module from it, is on the lint rules page. The classes themselves are in the API reference.
