File created by custom build script is missing from the wheel

[mattdibi]

• [X] I am on the latest Poetry version.
• [X] I have searched the issues of this repo and believe that this is not a duplicate.
• [X] If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Ubuntu 19.10 x86_64
• Poetry version: Poetry version 1.1.6

Issue

When running poetry build for the first time the file (version.py) built by my custom build script (version_info.py) isn't added in the wheel sources resulting in a broken build.

Expected file tree:

project-name-0.0.0
├── project-name
│   └── version.py
├── PKG-INFO
├── pyproject.toml
├── setup.py
└── version_info.py

Actual file tree:

project-name-0.0.0
├── project-name
├── PKG-INFO
├── pyproject.toml
├── setup.py
└── version_info.py

If i run poetry build a second time the file is added to the wheel as expected.

Am I missing something obvious?

I was trying to do exactly what you were with some shell scripts, googled a more native solution - found this issue and it looked great until I realised it's not working. Subscribed anyway.
