Build error when packages format is set and inconsistent tree structure

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Ubuntu 20.04.3 LTS

• Poetry version: 1.1.13

Issue

Hi , I am having some trouble trying to build my project with poetry.

I have following structure:

$ tree .
.
├── dist
│   ├── mypackage-0.1.0-py2.py3-none-any.whl
│   └── mypackage-0.1.0.tar.gz
├── pyproject.toml
└── src
    └── foo
        ├── bar
        │   └── __init__.py
        └── __init__.py

With:

[tool.poetry]
name = "mypackage"
version = "0.1.0"
description = "For test"
authors = ["Ghiles Meddour"]
packages = [
    { include = "foo", from = "src" }
]

1 - Build error when packages format is set to a single value

With that poetry build works fine, but I have an error with:

packages = [
    { include = "foo", from = "src", format = "sdist" }
]

Or

packages = [
    { include = "foo", from = "src", format = "wheel" }
]

Gives:

$ poetry build -vvv
Using virtualenv: /home/user1/.cache/pypoetry/virtualenvs/mypackage-hFh4EyFE-py3.8
Building mypackage (0.1.0)

Note that build works fine with format = ["sdist", "wheel"]

2 - Inconsistent tree structure

With:

packages = [
    { include = "foo", from = "src" }
]

I have:

Start with poetry/_vendor/py3.8/poetry/core/masonry/utils/module.py and the build path shown in poetry/console/commands/build.py. Reproduce both package configurations with poetry build -vvv, then inspect the wheel and source archive contents. Done means single-value formats build successfully and the package tree remains consistent when both formats are specified.
