Comments should really use '#', since it is shell. Also, we avoid
telling users to clone the git repo since 1) this is basically implicit
already and 2) it encourages them to checkout master instead of using
the latest release. This is especially helpful when the document is
referenced from http://grpc.io/docs since they specify checking out the
latest release (which is much easier to maintain when using jekyll which
is not an option here).
The examples are no longer part of the normal build, although they are
built with Travis. The examples now include their own copy of the gradle
wrapper to ease usage from IDEs which can now properly detect the
correct version of gradle to use.
The build files were generated using "gradle init" and "mvn
archetype:generate" and then modified following our README.
Fixes#1414
