调研方向

使用列出的 proto imports、buf template 和 buf generate --template buf.gen.additional.yaml --include-imports 重现该问题。检查生成的 mypackage.py 和输出树，然后将失败的 from .google import protobuf 与预期的 imports 进行比较；当列出的 Google packages 的生成 imports 可以解析时，即表示完成。

由索引模型根据 Issue 内容生成。

描述

bug investigation needed
Summary

from .google import protobuf which doesn't exist

Reproduction Steps

I’m facing an issue with the imported packages, my protofile has some import like this:

syntax = "proto3";

package mypackage;
import "google/api/annotations.proto";
import "google/api/client.proto";
import "google/api/field_behavior.proto";
import "google/protobuf/field_mask.proto";
import "google/api/resource.proto";
import "google/protobuf/empty.proto";
import "google/protobuf/timestamp.proto";
//import "validate/validate.proto";
import "protoc-gen-openapiv2/options/annotations.proto";

I’m running the code generation with buf:

version: v1
managed:
  enabled: true
plugins:
# Python
- plugin: buf.build/community/danielgtaylor-betterproto:v1.2.5
  out: _gen/pythonbproto2

and the command to run it is: buf generate --template buf.gen.additional.yaml --include-imports
The generated files are like this:

tree mypackage/api/proto/_gen/pythonbproto2

├── __init__.py
├── google
│   ├── __init__.py
│   └── api.py
├── grpc
│   ├── __init__.py
│   └── gateway
│       ├── __init__.py
│       └── protoc_gen_openapiv2
│           ├── __init__.py
│           └── options.py
└── mypackage

However the generated file mypackage.py is expecting a relative dir called google.protobuf which couldn’t be found, it has only the api.py not protobuf.
from .google import protobuf

Expected Results

The imported packages are properly handled. In the normal protoc way of generation, google.protobuf is a package and is imported directly like this: from google.protobuf import empty_pb2 as google_dot_protobuf_dot_empty__pb2

Actual Results

A relative import which doesn't exist: from .google import protobuf

System Information

protoc --version
libprotoc 24.3

buf --version
1.21.0

version: v1
managed:
  enabled: true
plugins:
# Python
- plugin: buf.build/community/danielgtaylor-betterproto:v1.2.5
  out: _gen/pythonbproto2

I'm not able to use normal command line to generate this:

protoc -I . --python_betterproto_out=lib mypackage.proto 
google/api/annotations.proto: File not found.
google/api/client.proto: File not found.
google/api/field_behavior.proto: File not found.
