Gradle: download Dependencies of included aar-library

Question

I wrote a library-project cameraBarcodeScanner that is built into an aar file. This library has the following dependencies defined in its build.gradle:

Answer 1

The aar file doesn't contain the nested (or transitive) dependencies and doesn't have a pom file which describes the dependencies used by the library.

It means that, if you are importing a aar file using a flatDir repo you have to specify the dependencies also in your project.

You should use a maven repository (you have to publish the library in a private or public maven repo), you will not have the same issue.
In this case, gradle downloads the dependencies using the pom file which will contains the dependencies list.
