Pants v2: The ergonomic build system

Welcome to the Pants v2 documentation hub!

Pants v2 is a fast, scalable, user-friendly build system for growing codebases. It's currently focused on Python, with support for other languages coming soon.

Here you'll find guides to help you get started with Pants v2, comprehensive documentation on how to configure, run and customize Pants v2, and information on how to get help from the Pants community.

Get Started

Configuration for roots of source trees.

Config section: [source]

Basic options


Advanced options


--source-root-patterns="[["pattern1", "pattern2", ...], ["pattern1", "pattern2", ...], ...]"

A list of source root suffixes. A directory with this suffix will be considered a potential source root. E.g., `src/python` will match `<buildroot>/src/python`, `<buildroot>/project1/src/python` etc. Prepend a `/` to anchor the match at the buildroot. E.g., `/src/python` will match `<buildroot>/src/python` but not `<buildroot>/project1/src/python`. A `*` wildcard will match a single path segment, e.g., `src/*` will match `<buildroot>/src/python` and `<buildroot>/src/rust`. Use `/` to signify that the buildroot itself is a source root. See


--source-marker-filenames="[filename, filename, ...]"
default: []

The presence of a file of this name in a directory indicates that the directory is a source root. The content of the file doesn't matter, and may be empty. Useful when you can't or don't wish to centrally enumerate source roots via `root_patterns`.
