To build the examples, run in this directory:

$ ../gradlew installDist

This creates the scripts hello-world-server, hello-world-client, route-guide-server, and route-guide-client in the build/install/grpc-examples/bin/ directory that run the examples. Each example requires the server to be running before starting the client.

For example, to try the hello world example first run:

$ ./build/install/grpc-examples/bin/hello-world-server

And in a different terminal window run:

$ ./build/install/grpc-examples/bin/hello-world-client

That's it!
