目前的Eclipse都集成了ant,本文图示如何在eclipse下使用ant
1.新建Java Project-新建Java文件HelloWorld.java
HelloWorld.java
package example;
public class HelloWorld {
    public static void main(String[] args) {
       System.out.println("Hello World");
    }
}
 
2.在工程根目录下新建build.xml
build.xml
<?xml version="1.0" encoding="utf-8"?>
<project default="main" basedir=".">
    <target name="main" depends="compile, compress" description="Main target">
       <echo>Building the .jar file.</echo>
    </target>
    <target name="compile" description="Compilation target">
       <javac srcdir="${basedir}/src/example" />
    </target>
    <target name="compress" description="Compression target">
       <jar jarfile="HelloWorld.jar" basedir="${basedir}/src/example" includes="*.class" />
    </target>
</project>
此脚本文件内容是编译/src/example下的java文件,并就地生成class文件,将这个class文件打成jar包,HelloWorld.jar
此时工程的目录结构如下图所示:
Eclipse下使用Ant_Eclipse
右键选中HelloAnt工程,选择Properties
Eclipse下使用Ant_职场_02
选择Builders-New…,选择Ant Build
NameAnt_Builder
Buildfile${workspace_loc:/HelloAnt/build.xml}
Base Directory${workspace_loc:/HelloAnt}
(按“Browse Workspace”选择工程根目录)
Eclipse下使用Ant_休闲_03
Builder面板中钩上Ant_Build,去掉Java Builder,即可编译执行。
每次编译时,右键build.xml,选择Run As-Ant Build
Eclipse下使用Ant_Ant_04
此示例工程编译结果:
Buildfile: D:\dev\Workspaces\J2EE\HelloAnt\build.xml
compile:
compress:
main:
     [echo] Building the .jar file.
BUILD SUCCESSFUL
