PyBuilder is a software build automation tool written in pure Python mainly targeting Python ecosystem. It is based on the concept of dependency-based programming but also comes along with powerful plugin mechanism that allows the construction of build life-cycles similar to those known from other famous build tools like Apache Maven and Gradle.

PyBuilder runs on Python 3.7 to 3.12 and PyPy. Every commit is tested via GitHub Actions on CPython 3.7, 3.8, 3.9, 3.10, 3.11, 3.12 and PyPy on Linux, MacOS (with and without Homebrew) and Windows.

v0.13.6 is the last version supporting Python 3.6.

v0.12.x still supports Python 2.7, and 3.5 but is no longer maintained.

v0.11.x still supports Python 2.6, 3.3 and 3.4 but is no longer maintained.
