Why libs with runtime scope are added to debugCompileClasspath?

If I add my lib to the project, and run command :

> gradlew -q app:dependencies --configuration debugCompileClasspath > app_dependencies_compile.txt

why does com.github.kolyall:utils:1.0.4 lib get the com.android.support:appcompat-v7 lib (and others) with runtime scope in CompileClasspath? If their scope is supposed to be runtime, why are they added to CompileClasspath?

Output is:

Before Gradle 5.0 gradle didn't support IMPROVED_POM_SUPPORT, so it was treating all transitive dependencies as compileby default. (non-jar packaging was unsupported.)

Related Gradle Bug

This was fixed in Gradle 5.0, where IMPROVED_POM_SUPPORT was made a default behavior.

Although it's not compulsory, it's a good practice to tell gradle that provided dependency is android archive use

implementation 'com.github.kolyall:utils:1.0.4@aar'{
    transitive=true
}

while declaring dependency in gradle. Notice @aar after the version of library

now after upgrading gradle to version 5.0 or higher,

compileClasspath output is

+--- com.google.code.gson:gson:2.8.5
+--- org.apache.commons:commons-lang3:3.8.1
+--- io.reactivex:rxjava:1.1.0
\--- com.github.kolyall:utils:1.0.4
     \--- net.danlew:android.joda:2.8.2
          \--- joda-time:joda-time:2.8.2
