Use of Jakarta-ant (Java Compilation tool)

Compile One: Introduction:
Ant is a compilation tool for Jakarta, and if you understand the makefile under Linux/unix you'll be very easy to
Understand the use of ant. Ant is best for you to use UltraEdit (EditPlus) to write Java programs, and then you use ant to compile, and Javadoc, to generate a Jar,war, The implementation of the file copy can be in Build.xml through different tager to achieve, or very convenient one Dongdong strongly recommended is to use.
Two: Download
You can download from the address below to ant, current version: 1.41
http://jakarta.apache.org/builds/jakarta-ant/release/v1.4.1/bin/

Three: Installation
A:) Windows
1: Unzip the file you downloaded, there will be a jakarta-ant (version number) directory generated, renamed him Ant
2:copy ant directory to the location you want.
3: Add in environment variable: Ant_home=ant installation directory, add $ant_home$\in in path; Note that you must also have the JDK installed and add the JAVA_HOME environment variable, plus $java_home$\in in the early path;

B:) Linux/unix
1: Unzip the file you downloaded, there will be a jakarta-ant (version number) directory generated, renamed him Ant
2:copy ant directory to the location you want.
3: Add in environment variable: Ant_home=ant installation directory, add $ant_home$\in in path; Note that you must also have the JDK installed and add the JAVA_HOME environment variable, plus $java_home$\in in the early path; Implement modify environment variable you need to modify the. bash_profile file.
As follows
Ant_home=/usr/local/ant
Java_home=/usr/local/jdk
Path= $PATH: $HOME/bin:/usr/local/ant/bin:/usr/local/jdk/bin

Export PATH ant_home Java_home

IV: Writing Build.xml
Build.xml rather Linux under the makefile, the implementation of the specific in Build.xml.
Let me give an example to illustrate.
Build.xml
