This document discusses the build tool Gradle. It notes that while Ant and Maven provide build functionality, they have limitations. Gradle addresses these by providing faster, more concise builds with a Groovy DSL. It is flexible, integrates with Ant, supports dependencies, and is programmable. The document provides examples of basic Gradle usage and recommends resources for learning more.
