detached does not work with EXTRA_INDEX_URL

[RichardOberdieck]

Description

• When using detached=true, the EXTRA_INDEX_URL is ignored. Using hatch 1.14.0

To reproduce

1. hatch new test-detached
2. Add this to the pyproject.toml

[tool.hatch.envs.default.env-vars]
PIP_INDEX_URL = "https://pypi.python.org/simple/"
PIP_EXTRA_INDEX_URL = <a-private-index>

[tool.hatch.envs.detached]
detached = true
dependencies = ["requests", "click", "pymsteams", "<package-name-only-found-in-extra-index>"]

[tool.hatch.envs.detached.scripts]
checking = "python -m checking {args}"

3. Run hatch run detached:checking

Result

ERROR: Ignored the following versions that require a different python version: 0.2.5 Requires-Python >=3.9
ERROR: Could not find a version that satisfies the requirement <package-name-only-found-in-extra-index> (from versions: none)
ERROR: No matching distribution found for <package-name-only-found-in-extra-index>

Expected

It should not fail

Workaround

Remove detached=true

[RichardOberdieck]

I/my colleague actually figured out: detached really is completed detachment. This means that one needs to specify the env-vars again, even if they were defined in the default. So my example from above needs to be modified as follows (note the [tool.hatch.envs.detached.env-vars]):

[tool.hatch.envs.default.env-vars]
PIP_INDEX_URL = "https://pypi.python.org/simple/"
PIP_EXTRA_INDEX_URL = <a-private-index>

[tool.hatch.envs.detached]
detached = true
dependencies = ["requests", "click", "pymsteams", "<package-name-only-found-in-extra-index>"]

[tool.hatch.envs.detached.env-vars]
PIP_INDEX_URL = "https://pypi.python.org/simple/"
PIP_EXTRA_INDEX_URL = <a-private-index>

[tool.hatch.envs.detached.scripts]
checking = "python -m checking {args}"
```
