Buildr是一个简单直观的Java项目构建系统，在进行了10个月的开发并获得许多正面反馈之后，Apache基金会将会向Buildr敞开大门并最终接手这个项目，这将是Apache基金会的第一个Ruby项目。
Apache Buildr is a build system for Java-based applications, including support for Scala, Groovy and a growing number of JVM languages and tools. 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.
