Apache Buildr - Overview

Overview

Buildr is based on Ruby's build system Rake, and uses Ruby as a scripting language. It uses some project automation idioms from Maven like automated artifact management (Buildr is out-of-box compatible with Maven's repositories). As opposed to more imperative style of build systems like Ant, Buildr takes a more declarative approach in describing the project automation logic (similarly to Maven).

Though Buildr's general philosophy is similar to Maven, it uses Ruby's scripting possibilities to provide a much more flexible and customizable programming model, dramatically extending the tools in the hands of the developer. The user writes a Ruby build script, declaring a project, its sub-projects, artifacts, dependencies, packaging rules etc.. Based on these declarations, a list of standard targets are provided to compile or package the project, upload a prepared package to a remote repository, clean up the build results, run tests and so on. Hooks are provided to execute custom Ruby code before or after the standard targets, allowing the user to comfortably override any defaults and further specify the behavior of the standard targets. New, completely user-written targets can be added, written in Ruby, using its full scripting powers.
