Most changes are migrating from conventions to the equivalent extensions. JMH, AppEngine, and Jib plugins trigger future compatibility warnings with `--warning-mode all`. The movement of configurations was to allow sourceSets to create the configurations and then we just configure them. When configurations were before sourceSets, we'd implicitly create the configuration. The examples were _not_ updated to the newer Gradle, although the non-Android examples work with the newer Gradle. The Android examples use an older Android Gradle Plugin which will need to be upgraded first. https://github.com/grpc/grpc-java/issues/10445 |

gRPC Hostname Example
The hostname example is a Hello World server whose response includes its hostname. It also supports health and reflection services. This makes it a good server to test infrastructure, like load balancing.
The example requires 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.
Build the example
-
Build the hello-world example client. See the examples README
-
Build this server. From the
grpc-java/examples/examples-hostnamedirectory:
$ ../gradlew installDist
This creates the script build/install/hostname-server/bin/hostname-server that
runs the example.
To run the hostname example, run:
$ ./build/install/hostname-server/bin/hostname-server
And in a different terminal window run the hello-world client:
$ ../build/install/examples/bin/hello-world-client
Maven
If you prefer to use Maven:
-
Build the hello-world example client. See the examples README
-
Run in this directory:
$ mvn verify
$ # Run the server (from the examples-hostname directory)
$ mvn exec:java -Dexec.mainClass=io.grpc.examples.hostname.HostnameServer
$ # In another terminal run the client (from the examples directory)
$ cd ..
$ mvn exec:java -Dexec.mainClass=io.grpc.examples.helloworld.HelloWorldClient
Bazel
If you prefer to use Bazel, run from the grpc-java/examples directory:
$ bazel build :hello-world-client example-hostname:hostname-server
$ # Run the server
$ ./bazel-bin/example-hostname/hostname-server
$ # In another terminal run the client
$ ./bazel-bin/hello-world-client
