Unity external dependency manager resolution failed

Question

Hi, I have imported Firebase packages (FirebaseAuth, FirebaseStore, FirebaseFunctions & FirebaseAnalytics) but I am getting below error while running external dependency manager android resolution.

Resolution failed

 Failed to fetch the following dependencies:
 com.google.firebase:firebase-app-unity:+
 com.google.firebase:firebase-auth-unity:+
 
 
 UnityEngine.Debug:LogError(Object)

Hey everyone,

We had a very similar problem and stumbled upon your post when searching for the solution.

In our case, it was a conflict because some Firebase libraries were present under the UnityPackageManager, and some under the Assets folder.

The problem is described here (spoiler: conflicting m2repositories folders): https://github.com/firebase/quickstart-unity/issues/771

And the solution was to install everything via package manager, getting rid of the /Assets leftovers that were causing the conflict. For this, we used the this very detailed answer on this post: https://stackoverflow.com/questions/64111347/unity-and-firebase-package-manager-resolver-uninstalling-the-following-packag

Hope it help you as well!
