Transitive Library dependencies are not found in the application

Question

Say I have a library module which contains some 3rd party libraries like OkHttp. When I include this library in my application I was unable to use these 3rd party libraries.

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.

It doesn't make sense:

compile (name:'library-name', ext:'aar'){
    transitive=true
}

because the aar is without a pom file which describes the dependencies, then gradle is unable to add any dependencies because it can't know them.
