This document provides an overview of Ant, an open source build tool for Java projects. It discusses Ant's structure, how it works, and provides an example of using a build.xml file to build an eMemory project. Specifically, it notes that Ant allows compiling Java code automatically based on XML build files that define targets containing tasks to generate artifacts like JAR files. It also explains that each project's build file contains targets, which are made up of tasks, and that targets can be selected on the command line or a default will run.

How to utilize build.xml
Take eMemory for example

4. What is Ant?
A cross-platform build tool
Based on industry standards (Java and XML)
Compile Java code automatically
Open Source (development coordinated by the
Apache Jakarta project)
Generate jar, ear, war, zip files automatically

5. Structure of Ant
Project : a top level collection of targets
Property: an Ant variable
Target: a collection of tasks executed to
achieve a particular purpose (a goal)
Task: a unit of Ant execution (a step)

6. How Does Ant Work?
Each Project will have a build file (build.xml)
Each build file will contain one or more Targets
The Target to be executed:
Is either explicitly selected on the command
line
Or a project default Target is executed
6

7. How Does Ant Work?
Each Target is executed only once
Each Target will contain one or more Tasks
Some Tasks are executed conditionally
Tasks are implemented as Java classes
