Steps to reproduce

2. Go to Publisher
3. Links for com.google.api.core.ApiFuture are broken.
4. Go to Subscriber
5. Links for com.google.api.core.AbstractApiService are broken.
6. etc.

To help expedite this because ApiFuture is an important element in Pub/Sub:

com.google.api.core.ApiFuture can be found here: https://googleapis.github.io/api-common-java/1.1.0/apidocs/com/google/api/core/ApiFuture.html

But we direct people to a non-existing page here: http://googleapis.github.io/googleapis/java/all/latest/apidocs/com/google/api/core.ApiFuture.html
