Android cyclic gradle dependencies

Question

I am trying to generate a release APK for Project A. it has a dependency on 2 imported libraries B and C which are also mine. B also has a dependency on C. This creates a situation where A compiles C and also B compiles c. This is the error:

java.io.IOException: The same input jar [/Users/Jon/android-app-manager/app/libs/**] is specified twice.

How is it possible to let gradle know the dependency has already been compiled?

Answer 1

There is no cyclic dependency in your description:

ProjectA --> LibB --> LibC

Gradle can manage transitive dependencies . All you have to do is :

• declaring a compile dependency to LibC in LibB (you already did that)
• declaring a compile dependency to LibB in ProjectA (you already did that)
• removing the explicit declaration of the dependency to LibC in ProjectA (gradle will find this transitive dependency automatically)
