After having used Apache Builder for a week and extracted our Warbler-code into a bonafide extension, I’m sharing it with the community under the fetching name Barbler. Barbler integrates itself between the build and packaging stages of the Apache Builder lifecycle and makes calls into Warbler to automate WAR-file creation.

The only post you’re likely to find is one by Jonas Boner (see below). During subsequent revisions of both Terracotta as well as JRuby, the example had...
