build function is ignored

[ngoettin]

• Poetry version: 1.3.2
• Python version: 3.10.6
• OS version and name: Arch Linux (24.02.2023)
• pyproject.toml:

[tool.poetry]
name = "test"
authors = ["me"]
version = "0.1.0"
description = "test"

[tool.poetry.dependencies]
python = "^3.10"

[tool.poetry.build]
script = "build.py"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

I tried to use Cython with poetry and failed, because the build-function did not seem to be executed. To test this, I created a new package with the following structure:

.
├── build.py
├── pyproject.toml
└── test
    └── __init__.py

where the pyproject.toml is shown above and the build.py contains only the following:

print("Hi! (1)")

def build(setup_kwargs):
    print("Hi! (2)")

Upon building the project, however, the only output I get is

~/Documents/test ❯ poetry build
Preparing build environment with build-system requirements poetry-core
Building test (0.1.0)
Hi! (1)

but I expected to also see Hi! (2) in the output.

What am I doing wrong? I've looked e.g. in the pendulum sources and I don't see how the concept of what I did differs from the build files there.

generate-setup-file = true

probably

Thank you so much, this solved the issue for me!

I encountered the same problem. Where to put that generate-setup-file=true setting?

[ywu]

Never mind. I just figured out.

[tool.poetry.build]
script = "build.py"
generate-setup-file=true
