There has been quite a few reports from developers seeing failed builds due to missing gradle dependencies in Bintray JCenter. If its the same issue as described here, this will also reproduce locally by clearing your cache.

If your project is still not building after making these changes, take special note of the project name listed early in the build error. It's possible a sub-project or dependency also leverages it's own gradle dependencies. If it's developed by a 3rd party, try updating it or reaching out to the developer.
