Different behavior between pyproject-build and pyproject-build -w

[pawamoy]

I'm using pdm-backend to build my project. I noticed that when I run pyproject-build, the data files are not added to the wheel. But if I run pyproject-build -w or pyproject-build -w -s, then the data files are correctly added to the wheel 🤔

pyproject.toml

[build-system]
requires = ["pdm-backend"]
build-backend = "pdm.backend"

[project]
name = "pawamoy-testing"
description = "Testing this great template"
authors = [{name = "Timothee Mazzucotelli", email = "dev@pawamoy.fr"}]
license = {text = "ISC"}
readme = "README.md"
requires-python = ">=3.8"
dynamic = ["version"]

[project.scripts]
pawamoy-testing = "pawamoy_testing.cli:main"

[tool.pdm]
version = {source = "scm"}

[tool.pdm.build]
package-dir = "src"
editable-backend = "editables"

[tool.pdm.build.wheel-data]
data = [
    {path = "share/**/*", relative-to = "."},
]

Reproduction:

git clone https://github.com/pawamoy/repro-pyproject-build
cd repro-pyproject-build

Ah, sorry, the answer in the CLI help:

By default, a source distribution (sdist) is built from {srcdir} and a binary distribution (wheel) is built from the sdist.

Since the data files are not added to the sdist, they're not added to the wheel either.

Feel free to close!
