I have just started playing with google proto. When I try to compile proto file present in proto-java example, it does not generate any grpc file.
proto file, https://github.com/grpc/grpc-java/blob/master/examples/src/main/proto/hello_world.proto
terminal output,
rsonkhla@raman-OptiPlex-9020:~/sandbox/grpc-java/examples$ protoc --version libprotoc 3.0.0 rsonkhla@raman-OptiPlex-9020:~/sandbox/grpc-java/examples$ protoc --java_out=test/ -I../../grpc-java/examples ../../grpc-java/examples/src/main/proto/hello_world.proto rsonkhla@raman-OptiPlex-9020:~/sandbox/grpc-java/examples$ ls -R test/ test/: io
test/io: grpc
test/io/grpc: examples
test/io/grpc/examples: helloworld
test/io/grpc/examples/helloworld: HelloRequest.java
HelloResponse.java HelloWorldProto.java HelloRequestOrBuilder.java HelloResponseOrBuilder.java
Has anybody else faced this issue?
The command line you are showing does not enable the grpc plugin. You need to specify an _out argument for the grpc plugin, which enables the plugin and specifies where it should output files. Since the plugin is likely not in your PATH
, you also need to tell protoc how to find the plugin with --plugin
.
So you need to add two arguments:
--plugin=protoc-gen-grpc-java=path/to/protoc-gen-grpc-java --grpc-java_out=path/to/output/dir
For more info, see the gRPC compiler documentation.
