Android Gradle Dependency

I am using local aar files for one of our projects and have below Query. I have 2 libraries and 1 application.

2 libraries are: 1. TestLib2 2. TestLib1

1 Application is: 1. Test

I use a aar file created for TestLib2 and refer it using flatDir in TestLib1. I can access the functions present in TestLib2 without any problems.

Now I use a aar file created for TestLib1 and refer it using flatDir in Test. I can access only the functions present in TestLib1. For accessing TestLib2 i have to add it to Test application as one more Library.

So the dependency is like below:

Test
|_ TestLib1
   |_ TestLib2

Is the above possible in case of aar files?

Also in settings.gradle file for TestLib1 i mention to include

include ':app', ':testlib2-debug'

Where app refers to the TestLib1

The build.gradle file doesnt really have any flavors as such and i dont even have any restriction of using them as jar's since its containing only the java piece of code.

Any help on the same is much appreciated.

Update 1: I tried below as well in build.gradle of TestLib1 and Test. Still no luck.

dependencies {
    compile (name:'testlib2-debug', ext:'aar') {
        transitive = true;
    }
}

And for Test App

compile (name:'testlib1-debug', ext:'aar')  {
        transitive = true;
}

So i finally figured out a solution for this. It works for 2 level dependency mentioned above.

Create a jar file for Test Lib 2.

task clearJar(type: Delete) {
    delete 'build/outputs/loggingSDK.jar'
}

task makeJar(type: Copy) {
    from('build/intermediates/bundles/release/')
    into('build/outputs/')
    include('classes.jar')
    rename ('classes.jar', 'testlib2.jar')
}

makeJar.dependsOn(clearJar, build)

By using a the command
