IndexError with my .gitignore file when trying to build a Python package

[haimat]

Problem description

I am trying to package my Python project/library. So first I created a pyproject.toml file, following the official Python docs, using hatchling - no fancy stuff here. Then, after upgrading to the latest build version, I ran this command from within the root folder of my project:

$ python -m build
* Creating venv isolated environment...
* Installing packages in isolated environment... (hatchling)
* Getting build dependencies for sdist...
* Building sdist...
Traceback (most recent call last):

IndexError: no such group

ERROR Backend subprocess exited when trying to invoke build_sdist

I do have a .gitignore file in my root folder, however, it includes only the default Python project template from Github.

Any ideas what is causing this error?

Please open an issue: https://github.com/cpburnz/python-pathspec

For now you can: https://hatch.pypa.io/latest/config/build/#vcs

@ofek Done. As reference: https://github.com/cpburnz/python-pathspec/issues/64

@ofek I have followed your advice and tried it with the following option in my pyproject.toml file:

[tool.hatch.build]
ignore-vcs = true

Unfortunately that does not change anything, I get the same error as before.

[ofek]

show pyproject.toml

[haimat]

Ok I found the problem in my pyproject.toml file:

include = [
  "**"
]

As soon as I have removed this option, everything was fine again.
