build with dependencies in requirements.txt file

Hi,

is it possible to build with the dependencies in the requierments file instead of inside the pyproject.toml file?

the setuptools docs contain that feature as in BETA
https://setuptools.pypa.io/en/latest/userguide/pyproject_config.html

dependencies file subset of the requirements.txt format (# comments and blank lines excluded) BETA

So it could be like this:
dependencies = {file="requirements.txt"}

however build get offended by that :):

configuration error: `project.dependencies` must be array
DESCRIPTION:
    Project (mandatory) dependencies.

GIVEN VALUE:
    {
        "file": "requirements.txt"
    }

OFFENDING RULE: 'type'

DEFINITION:
    {
        "type": "array",
        "items": {
            "$id": "#/definitions/dependency",
            "title": "Dependency",
            "type": "string",
            "description": "Project dependency specification according to PEP 508",
            "format": "pep508"
        }
    }

In addition. Currently what I do is a bash script that includes running build, read out the requirements.txt file and includes the requirements as a list into the pyproject.toml

build doesn't use JSON Schema for data validation; the error you are seeing is coming from setuptools. Passing a file in directly as a value to dependencies is not supported by the project metadata spec. Please read the section on "Dynamic Metadata" from setuptools' documentation on how to accomplish this using setuptools.
