jcenter() VS mavenCentral()

• jcenter is a Java repository in Bintray, which is the largest repo in the world for Java and Android OSS libraries, packages and components.
• All the content in jcenter is served over a CDN (content delivery network), with a secure https connection. Back in the time of the migration (Android Studio 0.8) The central maven 2 repository was HTTP only and HTTPS wasn’t supported. Maven central repository. (This might be one of the reasons as Google is a fan of HTTPs!).
• jcenter() is a superset of mavenCentral(), that encompasses many additional repositories and artifacts.
• The jcenter guys claim, that they have a better performance than maven central.
• Bintray has a different approach to package identification than the legacy Maven Central.
