Research direction

Start by reproducing the Kotlin DSL configuration shown in the issue, using gradle/HEADER.txt and the kotlin and kotlinGradle settings. Compare its behavior with the working Groovy DSL example and verify whether headers are added or replaced in the project’s .kt files; done means the Kotlin DSL applies the license header correctly.

Description

bug

If I use the config below, it works in Groovy Dsl project for kt fies

spotless {
    kotlin {
        ktlint()
        licenseHeaderFile(rootProject.file("gradle/HEADER.txt"))
    }
}

But if I just copy-paste it into Kotlin Dsl project, license headers will not be added or replaced into kt files.
