Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

Dubbo Java 3.2.13 oracle jdk 1.8 window10

Steps to reproduce this issue

proto: echo.proto

syntax = "proto3";

package echo;
option java_package = "dcloud.common";
option java_multiple_files = true;

service EchoService {
  rpc echo (EchoRequest) returns (EchoResponse) {}
  rpc echo2 (EchoRequest) returns (EchoResponse) {}
}

message EchoRequest {
  string message = 1;
  string name = 2;
}

message EchoResponse {
  string message = 1;
  repeated Trace traces = 2;
}

The generated code EchoServiceOuterClass class is not exists. EchoServiceOuterClass maby use Echo class replace Echo class code:

  private Echo() {}

The issue was resolved when I renamed the proto file name from echo.proto to echoService.proto

I checked the dubco-compile code and found that this might be the problem

What you expected to happen

Use the proto name when the proto file name is inconsistent with service, otherwise use service name +OuterClass

Anything else
