Added the kotlinter dependency in my gradle file.

plugins {
    id("org.jmailen.kotlinter") version "3.6.0"
}

I received the error NoSuchMethodError when attempting to run ./gradlew --lintKotlin. Turns out you need to be running gradle 6.8+ which comes with Kotlin 1.4 (Kotlin 1.3 is deprecated for the latest version of ktlint). So I upgraded gradle with ./gradlew wrapper --gradle-version 7.0. This resolved my kotlinter issues.

Also, you’ll want to update your IntelliJ settings such that wildcard imports are no longer used.
