Apache Ant (formerly Jakarta Ant) is a declarative, XML-based build tool created originally for Java projects. It provides a rich set of standard tasks for performing most common build operations, such as compiling Java source, building archives and running tests. Ant's functionality can be extended through custom tasks and macros.
Ant
Apache Ant is a Java open-source library and command-line tool whose mission is to drive processes described in XML build files as targets and extension points dependent upon each other. Most commonly, Ant is used to build Java applications.
It supplies a number of built-in tasks allowing to compile, assemble, test and run applications. Although primarily aimed at building Java applications, Ant can also be used effectively to build non-Java software, for instance C or C++ applications.
More generally, Ant can be used to pilot any type of process which can be described in terms of targets, tasks, and macros. It's a standard and effective framework which transforms a development structure of project to a deployment structure.
Ant was historically meant as a replacement and Java counterpart for the Unix Make build utility.

Example
Hello, World!
A build.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<project name="HelloWorld" default="world" basedir=".">
<target name="world" depends="message" description="outputs a friendly message">
<echo message="World!" />
</target>
<target name="message">
<echo message="Hello, " />
</target>
</project>
This project can be run from the directory containing the build.xml file by just typing:
ant- or
ant -f build.xml
The list of available self-documenting targets can be viewed with ant -p.
