android - Fabric maven repo causes slow gradle builds

Question

After upgrading from using the Crashlytics maven repo to the new Fabric maven repo and gradle plugin, my gradle builds have become incredibly slow.

The problem seems to be caused by the Fabric maven repo returning a 401 unauthorized error whenever gradle tries to resolve a dependency:

The old Crashlytics maven repo did not return these results.

Has anyone had a similar error, or found a fix?

Hemal from Fabric here.

Find this in build.gradle (should be 2 instances):

?maven { url 'https://maven.fabric.io/repo' }

and replace with:

maven { url 'https://maven.fabric.io/public' }
