detektMain is noisy "Ignoring a file detekt cannot handle"

[BraisGabin]

Expected Behavior

This kind of messages doesn't appear

> Task :common:core:detektDebugUnitTest
Ignoring a file detekt cannot handle: /Users/brais.gabin/projects/XXXXX/Class.java

Current Behavior

If I run ./gradlew detekt this messages never appear. But if I run ./gradlew detektMain or ./gradlew detektTest they do appear.

Context

Now that we have support to Android variants I'm moving my detekt configuration to use detektMain instead of detekt so I can use Type resolutions

I think this line results into the whole src/main/kotlin directory instead of a set of kotlin files like the plain detekt task does.
No the Gradle task must pass really plain java files to core.

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

Line 27 in 5e03bd9

setSource(kotlinSourceSet.kotlin.files)

This warning is from detekt-core. We could change info to debug:

detekt/detekt-core/src/main/kotlin/io/gitlab/arturbosch/detekt/core/KtTreeCompiler.kt

Line 31 in 5a0fe62

settings.info("Ignoring a file detekt cannot handle: $path")

We should just pass kotlin files from gradle to core.

The original issue is still there at 1.16.0-RC2

@Jacks0N23 Can you provide a reproducer? Also is the issue happening only with Type Resolution or also with the plain detekt task?

[Jacks0N23]

I have a production project with many modules
some of them contains java and kotlin code in common src/main/java source set
every module have connected configured detekt plugin
when I'm run detekt or detektMain or detektBaseline I see many lines like:

Ignoring a file detekt cannot handle: /Users/me/StudioProjects/myProject/sources/commons/common-dao/src/main/java/my/company/package/common_dao/DaoUtils.java
and so on…

also I saw files from res/ folder. Yes, I could exclude those packages, but why detekt doesn't filter them at configuration?
Also I would notice that I have default input param, didn't override it
