Can an AAR include transitive dependencies?

Question

So, right now I have a Library project, say project Foo that depends on a library like OkHttp.

Now, the Foo has a maven buildstep that generates an AAR and pushes it up to a public place.

So now lets say I have project B, we'll call it Bar. Bar is an Android application, and Bar depends on Foo.

Well, I have that. However, when I make a call to a public static function in Foo from Bar that calls OkHttp, I get this message:

java.lang.NoClassDefFoundError: com.squareup.okhttp.OkUrlFactory
            at com.foo.sdk.utils.OkHttpStack.<init>(OkHttpStack.java:15)

So, is such a thing possible? Or will Bar need to manually depend on OkHttp as well as any other dependencies Foo has?

Answer 1

So, it took a little while but I found what I was looking for. It just happened to be the way I was wording my searches.

This lesser-seen answer was exactly what I was looking for:

Transitive dependencies not resolved for aar library using gradle

Essentially, I needed to add a

transitive = true

to the build.gradle of Bar

ex:

compile ('com.foo:FOO:1.0.0@aar'){
       transitive=true
}

This way it includes all of my transitive libraries.

Note, however, that this may actually cause conflicts between dependencies (especially local ones) which can be resolved using an 'exclude' tag.
