Hey! These docs are for version 2.10, which is no longer officially supported. Click here for the latest version, 2.17!


A publishable Python setuptools distribution (e.g. an sdist or wheel).

See Building distributions.

Backend: pants.backend.python


type: Iterable[str] | None
default: None

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].

This augments any dependencies inferred by Pants, such as by analyzing your imports. Use ./pants dependencies or ./pants peek on this target to get the final result.

See Targets and BUILD files#target-addresses and Targets and BUILD files#target-generation for more about how addresses are formed, including for generated targets. You can also run ./pants list :: to find all addresses in your project, or ./pants list dir: to find all addresses defined in that directory.

If the target is in the same BUILD file, you can leave off the BUILD file path, e.g. :tgt instead of helloworld/subdir:tgt. For generated first-party addresses, use ./ for the file path, e.g. ./main.py:tgt; for all other generated targets, use :tgt#generated_name.

You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.


type: str | None
default: None

A human-readable description of the target.

Use ./pants list --documented :: to see all targets with descriptions.


type: Dict[str, Dict[str, str]] | None
default: None

Any entry points, such as console_scripts and gui_scripts.

Specify as a nested dictionary, with a dictionary for each type of entry point, e.g. console_scripts vs. gui_scripts. Each dictionary maps the entry point name to either a setuptools entry point ("path.to.module:func") or a Pants target address to a pex_binary target.


  "console_scripts": {
    "my-script": "project.app:main",
    "another-script": "project/subdir:pex_binary_tgt"

Note that Pants will assume that any value that either starts with : or has / in it, is a target address to a pex_binary target. Otherwise, it will assume it's a setuptools entry point as defined by https://packaging.python.org/specifications/entry-points/#entry-points-specification. Use // as a prefix for target addresses if you need to disambiguate.

Pants will attempt to infer dependencies, which you can confirm by running:

./pants dependencies <python_distribution target address>


type: bool | None
default: None

Whether to generate setup information for this distribution, based on analyzing sources and dependencies. Set to False to use existing setup information, such as existing setup.py, setup.cfg, pyproject.toml files or similar.


type: PythonArtifact

The setup.py kwargs for the external artifact built from this target.

You must define name. You can also set almost any keyword argument accepted by setup.py in the setup() function: (https://packaging.python.org/guides/distributing-packages-using-setuptools/#setup-args).

See Custom setup_py() kwargs for how to write a plugin to dynamically generate kwargs.


type: Iterable[str] | None
default: None
backend: pants.backend.experimental.python

List of URL addresses or Twine repository aliases where to publish the Python package.

Twine is used for publishing Python packages, so the address to any kind of repository that Twine supports may be used here.

Aliases are prefixed with @ to refer to a config section in your Twine configuration, such as a .pypirc file. Use @pypi to upload to the public PyPi repository, which is the default when using Twine directly.


type: bool
default: True

Whether to build an sdist for the distribution.


type: Dict[str, Iterable[str]] | None
default: None

PEP-517 config settings to pass to the build backend when building an sdist.


type: bool
default: False
backend: pants.backend.experimental.python

If true, don't publish this target's packages using Twine.


type: Iterable[str] | None
default: None

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run ./pants --tag='integration_test' test :: to only run on targets with that tag.


type: bool
default: True

Whether to build a wheel for the distribution.


type: Dict[str, Iterable[str]] | None
default: None

PEP-517 config settings to pass to the build backend when building a wheel.
