Java gRPC，嵌套类不生成

原件的一部分:

message GetTaskConfigsReply{
  message ConfigFileInfo{
    string name = 1;
    string path = 2;
    string modified_time = 3;
  }
  repeated ConfigFileInfo configs = 1;
}

大家好，我是Java新手，我想用GRPC远程控制另一个C#应用程序，这个C#应用程序会发送这个Java应用程序GetTaskConfigsReply，C#应用程序运行得很好，但是在Java中，ConfigFileInfo不能生成，我找不到这个类，该怎么修复呢？谢谢!

原件:

  rpc GetTaskConfigs(GetTaskConfigsRequest) returns (GetTaskConfigsReply);
  
}

Java代码:

 private static List<ConfigFileInfo> GetTaskConfigs(RemoteControlBlockingStub remoteControlBlockingStub) {
        GetTaskConfigsRequest request = GetTaskConfigsRequest.newBuilder().build();

        GetTaskConfigsReply reply = remoteControlBlockingStub.getTaskConfigs(request);
        List<ConfigFileInfo> configFileInfos = new ArrayList<ConfigFileInfo>();
        for (int i = 0; i < reply.getConfigsCount(); i++) {
            configFileInfos.add(reply.getConfigs(i));
        }
        return configFileInfos;
    }
