Android : Create AAR with dependentant library Projects

We are creating an SDK Project with below modules [And its dependencies are mentioned below]

• App [Android Application]
• Dev-sdk [Android Library]
• Dev-sdk1 [Android Library]
• Dev-sdk2 [Android Library]

App (build.gradle)

dependencies {
    compile project(path: ':Dev-sdk')
}

Dev-sdk (build.gradle)

dependencies {
    compile project(path: ':Dev-sdk1 ')
}

Dev-sdk1 (build.gradle)

dependencies {
    compile project(path: ':Dev-sdk2')
}

Dev-sdk2 (build.gradle)

dependencies {
    // No Dependencies
}

When I try to create aar for "Dev-sdk", It doesn't have included dependencies.

is there any way to create AAR for module Dev-sdk with all its dependencies ?
