Refactor the proto file `helloworld_streaming.proto` because Bazel and Gradle have incompatible base directory for proto imports. Bazel's proto import is relative to WORKSPACE, whereas Gradle proto plugin's is relative to `${sourceSet}/proto/`. In `helloworld_streaming.proto` file, `import helloworld.proto` does not work for Bazel. If `import src/main/proto/helloworld.proto`, that works for Bazel, but Gradle and Maven would fail. Some workarounds are very hacky, so use independent proto without imports instead to avoid this issue.

grpc Examples
The examples require grpc-java to already be built. You are strongly encouraged to check out a git release tag, since there will already be a build of grpc available. Otherwise you must follow COMPILING.
You may want to read through the Quick Start Guide before trying out the examples.
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/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/examples/bin/hello-world-server
And in a different terminal window run:
$ ./build/install/examples/bin/hello-world-client
That's it!
Please refer to gRPC Java's README and tutorial for more information.
Maven
If you prefer to use Maven:
$ mvn verify
$ # Run the server
$ mvn exec:java -Dexec.mainClass=io.grpc.examples.helloworld.HelloWorldServer
$ # In another terminal run the client
$ mvn exec:java -Dexec.mainClass=io.grpc.examples.helloworld.HelloWorldClient
Bazel
If you prefer to use Bazel:
(With Bazel v0.4.5 or above.)
$ bazel build :hello-world-server :hello-world-client
$ # Run the server:
$ bazel-bin/hello-world-server
$ # In another terminal run the client
$ bazel-bin/hello-world-client
Unit test examples
Examples for unit testing gRPC clients and servers are located in examples/src/test.
In general, we DO NOT allow overriding the client stub.
We encourage users to leverage InProcessTransport as demonstrated in the examples to
write unit tests. InProcessTransport is light-weight and runs the server
and client in the same process without any socket/TCP connection.
For testing a gRPC client, create the client with a real stub using an InProcessChannel, and test it against an InProcessServer with a mock/fake service implementation.
For testing a gRPC server, create the server as an InProcessServer, and test it against a real client stub with an InProcessChannel.
The gRPC-java library also provides a JUnit rule, GrpcServerRule, to do the starting up and shutting down boilerplate for you.
