I would like to create an empty (meta)package using the poetry tool, mainly to simplify bringing together a list of dependencies. If I create my project.toml as follows:
[build-system]
requires = ["poetry"]
[tool.poetry]
name = "metapackage"
version = "1.0.0"
description = "My empty metapackage"
authors = ["Me"]
license = "MIT"
[tool.poetry.dependencies]
numpy = "*"
Then execute poetry build, I get an error:
$ mkdir -p metapackage
$ python -m poetry build --no-interaction --format wheel -vvvUsing virtualenv: /Users/duncan/opt/miniconda3/envs/py37
Building metapackage (1.0.0)
[ValueError]
metapackage is not a package.

Am I missing something to tell poetry that this package has no contents?
Addendum: I'm jusy using poetry as a means to creating a .dist-info directory populated with metadata, so that pip sees the installed metapackae, if there's a better tool for that, I'm happy to switch.
With setuptools it could look like the following:
pyproject.toml
[build-system]
build-backend = "setuptools.build_meta"
requires = ["setuptools"]
setup.cfg
[metadata]
name = metapackage
version = 1.0.0
description = My empty metapackage
authors = Me
license = MIT
[options]
install_requires =
numpy
Note how the options packages, py_modules, scripts, and ext_modules are not populated.
