 Review comment:
   I highly doubt that a gradle user will not know where to find the file, but why not...

> Having a proper project template helps a lot in getting dependencies right. For example,
setting the core dependencies to "provided", the connector / library dependencies to "compile",
etc.
> The Maven quickstarts are in good shape by now, but there is none for Gradle and Gradle
users to get this wrong quite often.
