Add Nexus Mirrors to gradle builds with Init Script

init.gradle

// Replace the location of the nexus repository with your specific location.
// To enable this:  gradlew build -I init.gradle
// This will now have gradle use the mirrors first and jcenter and other repositories second if it can't find the artifacts.
// Make sure your mirror Jcenter in your nexus repository.
