Apache Buildr

Apache Buildr is a build system for Java-based applications that also supports Scala, Groovy, and other JVM languages. It is designed to be simple, fast, and extensible, using Ruby as its scripting language. Buildr emphasizes minimal configuration, intuitive syntax, and powerful dependency management, making it a compelling alternative to tools like Ant and Maven. Though retired and archived in the Apache Attic, Buildr remains a notable example of a Ruby-based build automation tool for JVM projects.
