The repro is somewhat unclear.
The package structure is uses `abc` but the protobuf sources use `adc`; I
assume both should be the same.
In `share.proto`, `message Test` contains no fields and fields contain
values, so the `Test` message contains no values and isn't useful.
The `detect.proto` contains no messages and so isn't useful either.
If instead the following structure is used:
```
.
├── com
│ └── abc
│ ├── depart
│ │ └── detect.proto
│ └── protobuf
│ └── share.proto
└── main.py
```
And:
`detect.proto`:
```
syntax = "proto3";
package com.abc.depart;
import "com/abc/protobuf/share.proto";
message X{
com.abc.protobuf.Test test = 1;
}
```
And:
`share.proto`:
```
syntax = "proto3";
package com.abc.protobuf;
message Test{
string value = 1;
}
```
Because, there's a single protopath (`${PWD}` or `.`), we can use one
`protoc` command to compile to Python sources:
```bash
protoc \
--proto_path=${PWD} \
--python_out=${PWD} \
--pyi_out=${PWD} \
${PWD}/com/abc/depart/detect.proto \
${PWD}/com/abc/protobuf/share.proto
```
and e.g. `main.py`:
```python3
from com.abc.depart import detect_pb2
x = detect_pb2.X()
x.test.value = "foo"
print(x)
```
Yields:
```console
test {
value: "foo"
}
```
