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 2.7 to 3.9 and PyPy. Every commit is tested on CPython v2.7, 3.5, 3.6, 3.7, 3.8, 3.9 and PyPy on Linux, OSX and Windows via Travis CI.

v0.11.x still supports Python 2.6, 3.3 and 3.4 but is no longer maintained.

No Virtual Environments Feature in 0.12.9

Due to requests of Anaconda environment users PyBuilder version 0.12.9 introduced a --no-venvs option. This option turns off all Python virtual environment management implemented in 0.12.x for those users who prefer (or must) manager their own virtual environments.

Version 0.12.0 Released!

After many months of intense work, PyBuilder 0.12.0 has been released fixing most of the outstanding issues as well as introducing a number of breakthrough features for virtual environment management, unit testing and coverage.
