Hey, I need to ask that question, as it already takes too long for me to solve this.
So I’m having an android project with multiple modules and I want to execute detekt for all modules, but skipping ‘build’ and ‘resources’ directories. Hence my configuration

detekt {
    input = files(escapedProjectDir)
    baseline = file("$escapedRootProjectDir/config/detekt/detekt-baseline.xml")
    config = files("$escapedRootProjectDir/config/detekt/detekt.yml")
    autoCorrect = false
    parallel = true
}

tasks.withType(io.gitlab.arturbosch.detekt.Detekt) {
    exclude '**/resources/**'
    exclude '**/build/**'
}

But it keeps checking build directory. What’s wrong?

I’m using detekt 1.18.0-RC2

So I couple of questions:
• What is escapedProjectDir ?
• Why do you even need this custom configuration? Detekt will not scan the build folder by default.

[Karol Ksionek]

by default it will use ‘src/main/kotlin’ and I care for all flavors, ’src/test/, not to mention the fact that my project’s source code is still in ‘src/main/java’

[Karol Ksionek]

escpedProjectDir is valid path, pointing to project root

[Karol Ksionek]

escapedProjectDir is /Users/ksionekk/AndroidStudioProjects/project-android/
and detekt finds an issue
MaximumLineLength - [] at /Users/ksionekk/AndroidStudioProjects/project-android/auth/build/generated/source/kaptKotlin/debug/com/example/app/auth/api/authcheck/AuthCheckInfo_AuthorizedJsonAdapter.kt221

[gammax]

I see your situation. Just out of curiousity: have you considered using the other tasks such as detektDebug , detetkRelease, detetk<Flavor> as they have the input folders already set up for you.

[Karol Ksionek]

I’d like to stay with config that we had before, when using detekt 1.5.1, so task “detekt” running over all sources

[gammax]

Just as a FYI, detekt-gradle-plugin is designed with a per-project approach (i.e. one task per every module, according to the Gradle philosophy).

Having only a single task that runs over all your codebase can lead to situation like the one you’re facing.

Anyway, I believe you could try to replace your exclude **/build/** with:

exclude { element -> element.file.path.contains("build/") }

Please let me know if this helps 👍

[Karol Ksionek]

It doesn’t work for me. I’ve changed it to

tasks.withType(io.gitlab.arturbosch.detekt.Detekt) {
    exclude { element ->
        println("DEBUG $element")
        element.file.path.contains("build/")
    }
}

and DEBUG isn’t ever printed to the console

[gammax]

tasks.withType(io.gitlab.arturbosch.detekt.Detekt).configureEach{

☝️ I believe you missed a configureEach{

[Karol Ksionek]

even with configureEach issues are being reported

[Karol Ksionek]

and still => no “DEBUG” in logs

[gammax]

Ok I see. To help you further I need you to provide some sort of reproducer. If your project is open-source that would be 👌

If it’s not, you can use this template github.com/cortinico/kotlin-android-template/ and try to recreate your setup.

[Karol Ksionek]

ok, will do. BTW I’m using Gradle 6.6

[Karol Ksionek]

here you go https://github.com/karolVimn/kotlin-android-template

[gammax]

Awesome. Looking into it

[gammax]

So the problem with the project you linked is that you’re applying Detekt inside subprojects{} and you’re running tasks.withType… at the top level project (that doesn’t have Detekt applied).

[gammax]

So if you move the tasks.withType inside the subprojects{} block it will work:

[gammax]

subprojects {
    apply {
        plugin("io.gitlab.arturbosch.detekt")
        plugin("com.github.ben-manes.versions")
    }

    detekt {
        input = files(escapedProjectDir)
        config = rootProject.files("config/detekt/detekt.yml")
        parallel = true
    }

    tasks {
        withType<io.gitlab.arturbosch.detekt.Detekt>().configureEach {
            exclude("**/build/**")
        }
    }
}

[gammax]

Is it working? @Karol Ksionek

[gammax]

Also as a side note: If you’re using a similar approach in your project as well, that’s extremely inefficient.

Specifically you’re duplicating the detekt work a lot of times, once for every module you have.

This means that if you have say 50 modules, you’r running Detekt on the whole codebase 50 times. Gradle will fail the first time if there is a violation, but in case of success it will actually run all the times.

[Karol Ksionek]

Yeah, sorry, I’ve missed the fact that my detekt configuration is on main level, not in subprojects section. So I’ve prepared wrong example, but since it started to work I’ve assumed that’s it. Few minutes ago I’ve found what the real issue is…
I’ve added

tasks.withType(io.gitlab.arturbosch.detekt.Detekt).configureEach {
    println("DEBUG - Doesn't enter here")
    it.exclude("**/build/**")
}

tasks.configureEach {
    if (it.name.contains("detekt")) {
        println("DEBUG Hello, I am here and can exclude! $it ${it.class}")
        it.exclude("**/build/**")
    }
}

And withType doesn’t exclude build dir, but checking by name does!
so looks like my issue is related to gradle itself. I have this configuration in separate file detekt.gradle - had no idea that it may have any meaning.
https://github.com/gradle/gradle-native/issues/742
Well… Gradle/Groovy - surprises on each corner….

Thanks for your help though!

[gammax]

External Gradle files (like a detekt.gradle) are a massive pain
