How can I use proto-google-common-protos in a quarkus project

[baozi-2019]

I have a multi module quarkus project like this. And proto-google-common-protos imported in center-api project.

├── center
│   ├── center-api
│   ├── src
│   │   └── main
│   │       └── resources
│   │           └── proto
│   │               ├── test.proto
│   │               └── user-service.proto
│   ├── center-service

user-service.proto

syntax="proto3";

option java_multiple_files = true;
option java_package = "org.baoiz.bs.acs.grpc";
option java_outer_classname = "UserServiceProto";
import "google/type/datetime.proto";

package user.service;

service UserGrpcService {

}

message UserInfoReply {
  string name = 1;
  google.type.DateTime aa = 2;
}

I want to use quarkus to generate grpc code. But datetime.proto can not be found.
If I change yaml config file like this:

generate-code:
    grpc:
    scan-for-proto: all

It compile error, because there are multiple helloworld.proto file.
How can I use proto-google-common-protos to create new proto file?
