Cannot exclude generated code

We are using the jooq gradle plugin to generate some kotlin code (https://github.com/etiennestuder/gradle-jooq-plugin) Obviously I would like to exclude this code from ktlint. Code gets generated in <project>/build/generated-src It seems this is impossible. Here is the attempt I made:

ktlint {
    version = libs.versions.ktlint.get()
    debug = true
    verbose = true
    filter {
        include { element ->
            println(element.file.path)
            println(!element.file.path.contains("generated-src"))
            !element.file.path.contains("generated-src")
        }
        exclude { element ->
            println(element.file.path)
            println(element.file.path.contains("generated-src"))
            element.file.path.contains("generated-src")
        }
    }
}

With the above kode ktlint still fails on the generated code.

Here is how I got it to work:

ktlint {
    filter {
        exclude { entry ->
            entry.file.toString().contains("generated")
        }
    }
}

I have a similar setup with a generated-src directory and for the life of me I could not make the plugin exclude that directory.

However, I found that if I: rm -rf .gradle and then ./gradlew ktlintCheck the exclusions worked just fine. This suggests to me that the plugin is simply re-running ktlint on the same files it failed on previously without re-applying the exclude filter.

Seems like a legit bug.
