DESCRIBE THE ISSUE IN DETAIL:

Im using a custom AsmClassVisitorFactory in order to transform local class files and dependencies. However it does not invoke a transformation on self-resolving dependencies such as JARs and AAR files that I add to the build like:

dependencies {
    implementation(fileTree(mapOf("dir" to "libs", "include" to listOf("*.jar", "*.aar"))))
    //implementation(files("libs/myaarlib-1.2.3.aar"))
}

Please take a look at the attached project where I have added a JAR and an AAR file to the build. In the buildSrc you will find an ExamplePlugin that uses the Instrumentation API and just prints the name of each class that is about to be transformed.

abstract class ExampleClassVisitorFactory :
        AsmClassVisitorFactory<ExampleParams> {

        override fun createClassVisitor(
            classContext: ClassContext,
            nextClassVisitor: ClassVisitor
        ): ClassVisitor {
            println("## transform class: "+ classContext.currentClassData.className)
            return nextClassVisitor
        }

        override fun isInstrumentable(classData: ClassData): Boolean {
            return true
        }
    }

I also print inputs and outputs of each task. You will notice that the transformation is applied to project classes, dependencies but not the included JAR and AAR file.

> Task :app:transformDebugClassesWithAsm
## transform class: com.android.build.example.minimal.MainActivity
## transform class: com.example.ExampleClass
## transform class: com.android.build.example.minimal.BuildConfig
## transform class: com.example.myaarlib.R <-- R file is transformed, MyAARlib.class not
## transform class: com.android.build.example.minimal.R
 inputs: 
    C:\workspaces\devtools\android-sdk\platforms\android-29\android.jar
    C:\workspaces\devtools\android-sdk\build-tools\30.0.3\core-lambda-stubs.jar
    C:\workspaces\gradle-recipes\BuildSrc\testAsmTransformApi\app\build\tmp\kotlin-classes\debug
    C:\workspaces\gradle-recipes\BuildSrc\testAsmTransformApi\app\build\intermediates\javac\debug\classes

    ...

STEPS TO REPRODUCE:

1. open project
2. gradlew assDebug
3. see log, notice the classes MyAARlib and MyClass are not transformed

Also attached is the Gradle log

If that's intended behavior, we would like to understand why these artifacts are excluded.
