   倒是没有报错。 
   org.apache.dubbo.gen.grpc.DubboGrpcGenerator dubbo的的代码里面生成grpc  代码的 maven插件代码  
   ```
   public class DubboGrpcGenerator extends AbstractGenerator {
   
       public static void main(String[] args) {
           if (false) {
               ProtocPlugin.generate(new DubboGrpcGenerator());
           } else {
               ProtocPlugin.debug(new DubboGrpcGenerator(),"D:\\Users\\guo.lin\\git\\cdubbo\\cdubbo-demo3\\src\\main\\proto\\Greeter.proto");
           }
       }
   }
   ```
   我传递proto 文件进去 然后有如下报错
   ```
   com.google.protobuf.InvalidProtocolBufferException$InvalidWireTypeException: Protocol message tag had invalid wire type.
   	at com.google.protobuf.InvalidProtocolBufferException.invalidWireType(InvalidProtocolBufferException.java:115)
   	at com.google.protobuf.UnknownFieldSet$Builder.mergeFieldFrom(UnknownFieldSet.java:551)
   	at com.google.protobuf.UnknownFieldSet$Builder.mergeFrom(UnknownFieldSet.java:514)
   	at com.google.protobuf.UnknownFieldSet$Builder.mergeFrom(UnknownFieldSet.java:633)
   	at com.google.protobuf.UnknownFieldSet$Builder.mergeFrom(UnknownFieldSet.java:295)
   	at com.google.protobuf.CodedInputStream$ArrayDecoder.readGroup(CodedInputStream.java:856)
   ```
   所以第二个参数需要传递什么进去才可以做到调试呢。
