It sounds good, however, there is also a way to completely automatically
release to Maven Central directly from Travis with Git commit messages
such as "[#DO_RELEASE]" or "[#DO_RELEASE][#2.0.0]". I've been using it
to release my projects in the Continuous Delivery process for a year or
so (and in general it works :) ).

Sample configuration:
(in fact just a few lines are required for the release process, others
are to satisfy Maven Central requirements, e.g. generated pom.xml elements).

I could also provide the release support as a backup plan.

Nevertheless, those are not the only possible way in the Gradle universe.
