Gradle detektBaselineMain task not creating baseline for particular folder structure

[tinder-kuldeeptanna]

Expected Behavior

Baseline file should be created when running detektBaselineMain for a module

Observed Behavior

Baseline file is not created when running detektBaselineMain for a module
(detektBaseline does create the baseline file for same module)

Steps to Reproduce

1. Clone https://github.com/ktanna/TestDetekt
2. Run ./gradlew :swipe-party:card-stack:data:detektBaselineMain
3. Notice no baseline file was created in swipe-party/card-stack/data folder.

Note: If you run ./gradlew :swipe-party:card-stack:data:detektBaseline, the baseline file will be created.

Context

We use baselines to allow to suppress warnings for legacy code. With this bug, some modules don't have baseline created.

Your Environment

I've briefly looked into this. The problem is that you used the src/main/kotlin folder. If you use instead src/main/java folder, it will work correctly.

When we register the Android tasks, we use javaDirectories from AGP.

detekt/detekt-gradle-plugin/src/main/kotlin/io/gitlab/arturbosch/detekt/internal/DetektAndroid.kt

Lines 118 to 119 in edabb6f

	registerDetektTask(taskName, extension) {
	setSource(variant.sourceSets.map { it.javaDirectories })

I haven't really looked deeply into this but seems like AGP is not properly returning the kotlin folder when we call .javaDirectories. Therefore we would have to patch it locally I believe. I'm unsure we're going to do it.

SourceProvider.getKotlinDirectories is added in Android Gradle Plugin 7.0.0, which drops Java 8. Therefore, we can't resolve this issue until #4130 is resolved.

Oh that's great news! One more reason to drop Java 8 then :)

Looks like fixed in #4554 isn't it?

Yes this can be closed 👍
