You need to specify --java_plugin_out=.. --plugin tells protoc where to find the plugin, but it doesn't cause protoc to run the plugin; the _out argument does that.

Note that --java_out is not for javanano. You would want to use --javanano_out instead. To enable javanano for gRPC, you should add nano=true to java_plugin_out: --java_plugin_out=nano=true:.

Also note that the plugin is no longer named "java_plugin" but instead "protoc-gen-grpc-java", so you may need to make sure the --plugin argument points to an executable file.

Take a look at the compiler documentation for more info.
