• 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: Manjaro Linux Latest
• Poetry version: 1.0.0b8
• pyproject.toml: https://github.com/pymedphys/pymedphys/blob/9b24bad2520684793b35193191cdb470809b8b05/pyproject.toml

Issue

It appears as though the following line within a .gitignore file is not being honoured by poetry build:

https://github.com/pymedphys/pymedphys/blob/9b24bad2520684793b35193191cdb470809b8b05/pymedphys/_app/.gitignore#L10

See the corresponding PyPI release which contains the build directory which should not have been included:

https://pypi.org/project/pymedphys/0.13.0.dev0/#files

Keen for any pointers on how to get this directory not included within the release artefact.

Cheers,
Simon
