How do you tell ktlint in android to exclude specific paths in the project?

Question

Currently when I want to format my code, I run this in the terminal in my android studio directory

https://github.com/pinterest/ktlint

./gradlew ktlintFormat

This command works great, but recently I added some folders into my project and the code in there is being checked by the ktlintFormat command. I wish to exclude those folders from being checked. Does anyone know if this is possible?

ktlint {
    filter {
        exclude("**/generated/**")
        include("**/kotlin/**")
    }
}

Doesn't work with JLLeitschuh/ktlint-gradle. See more here: github.com/JLLeitschuh/ktlint-gradle/issues/266. – Oberammergau

filter is not working with latest version – Kidskin

Answer 2

In general, العبد's answer is correct. However, as of 12.1.1 of the ktlint Gradle plugin this doesn't work.

A working alternative until this is fixed:

filter {
    exclude { element ->
        def path = element.file.path
        path.contains("/generated/") || path.contains("/kotlin/")
    }
}
