Buildr Project Incubation Status

This page tracks the project status, incubator-wise. For more general project status, look on the project website.

The Buildr project graduated on 2009-02-23


Buildr is a build system for Java applications written in Ruby. We wanted something that’s simple and intuitive to use, so we only need to tell it what to do, and it takes care of the rest. But also something we can easily extend for those one-off tasks, with a language that’s a joy to use. And of course, we wanted it to be fast, reliable and have outstanding dependency management.

These action items have to be checked for during the whole incubation process.

These items are not to be signed as done during incubation, as they may change during incubation. They are to be looked into and described in the status reports and completed in the request for incubation signoff.

Collaborative Development

  • Have all of the active long-term volunteers been identified and acknowledged as committers on the project?
  • Are there three or more independent committers? (The legal definition of independent is long and boring, but basically it means that there is no binding relationship between the individuals, such as a shared employer, that is capable of overriding their free will as individuals, directly or indirectly.)
  • Are project decisions being made in public by the committers?
  • Are the decision-making guidelines published and agreed to by all of the committers?

Licensing awareness

  • Are all licensing, trademark, credit issues being taken care of and acknowleged by all committers?


Things to check for before voting the project out.

Organizational acceptance of responsibility for the project

  • If graduating to a new PMC, has the board voted to accept it? Yes.

Incubator sign-off

  • Has the Incubator decided that the project has accomplished all of the above tasks?
  • Yes. The resolution to make Buildr a TLP has been approved in Dec. 2008.
