Constructor Details

#initialize(buildable, commit_id) ⇒ Builder

Instantiate the Builder, passing an object that understands the Buildable interface, and a commit_id.

You can pass :head as the commit id, in which case it will resolve to the head commit of the current branch (for example, “HEAD” under git, or the latest revision under svn)

Instance Method Details

#build ⇒ Object

This is where the magic happens:

  1. Check out the repo to the appropriate commit.

  2. Notify the buildable that the build is starting.

  3. Run the build script on it in the background.

  4. Reports the build back to the buildable.
