How to generate Protobuf in Java?

Question

Java

Hello everyone! I am almost new to both Java and Kotlin, but I have been working with buffer protocols for a long time. There is no way to correctly generate files through protoc, as unnecessary subfolders are created. Let's say I want the generated files to be in a package com.example.pb.test, and they are created in com.example.pb.test.test

the Project Structure like this:


Makefile in the pb folder:

compile:
  protoc --java_out=tutorial --kotlin_out=tutorial test.proto

test.proto

syntax = "proto3";

package tutorial;

option java_package = "tutorial";
option java_outer_classname = "AddressBookProtos";

message Person {
  optional string name = 1;
  optional int32 id = 2;
  optional string email = 3;

  enum PhoneType {
    MOBILE = 0;
    HOME = 1;
    WORK = 2;
  }

  message PhoneNumber {
    optional string number = 1;
    optional PhoneType type = 2;
  }

  repeated PhoneNumber phones = 4;
}

message AddressBook {
  repeated Person people = 1;
}

As a result, this is created here:


Please help!

PS I also changed java_package to com.lightswitch.contesttest.pb.tutorial, but in this case the whole name is duplicated
