This generates the Java interfaces out of the service definition from a .proto file.
Change to the compiler directory:
$ cd $GRPC_JAVA_ROOT/compiler
To compile the plugin:
$ gradle java_pluginExecutable
To test the plugin with the compiler:
$ gradle test
You will see a PASS if the test succeeds.
To compile a proto file and generate Java interfaces out of the service definitions:
$ protoc --plugin=protoc-gen-java_rpc=build/binaries/java_pluginExecutable/java_plugin \
--java_rpc_out="$OUTPUT_FILE" --proto_path="$DIR_OF_PROTO_FILE" "$PROTO_FILE"
To generate Java interfaces with protobuf nano:
$ protoc --plugin=protoc-gen-java_rpc=build/binaries/java_pluginExecutable/java_plugin \
--java_rpc_out=nano=true:"$OUTPUT_FILE" --proto_path="$DIR_OF_PROTO_FILE" "$PROTO_FILE"
