Trigger full rebuild of package before installation

[tibortakacs]

I have a package with a key.json data file in it. setup.cfg:

[options.package_data]
enigma = key.json

When I build it, it properly copies the data file into the package, and installs it into the relevant tox environment.

However, if I modify this content to enigma = key_missing.json, I would expect failure in tests due to the missing data file. Then, I renamed key.json to key_missing.json, and now both files are part of the package.

I think this is not a tox issue directly, but it would be great I could ensure that my package is completely re-built. What are you thoughts on that?

We do ensure this, if anything is a setuptools bug. I suggest using a more modern build backend, like hatchling.

Thank you, make sense. Is there an example how the default build backend can be replaced in tox?

[gaborbernat]

This is not tox specific. tox follows the Python specs. https://tox.wiki/en/latest/user_guide.html#packaging

Thank you, I am going to read it through.
