Make Your Builds More Groovy
This document provides an overview of build tools and discusses ways to make builds more flexible using Groovy. It covers common build pain points and provides examples comparing Ant, Gant, and Maven builds written in Java and Groovy for a StringUtils project. The examples demonstrate how Groovy can enhance traditional build tools by providing a more concise syntax, easier refactoring and testing of builds.
