安装ant，去http://ant.apache.org下载
配置环境变量（前提是配置了java环境变量）
ANT_HOME
G:\Software\ant1.9.7 //ant根目录
在PATH后添加
;%ANT_HOME%\bin //注意分号
cmd命令输入ant,结果为
Buildfile: build.xml does not exist! Build failed
表示安装成功
测试程序helloWorld
package test;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("HelloWorld");
}
}
在src目录下新建build.xml
<?xml version="1.0" ?>
<project name ="itProject" default="compile" basedir=".">
<target name="clean">
<delete dir="${basedir}/build"/>
</target>
<target name="compile" depends="clean">
<mkdir dir="${basedir}/build/classes"/>
<javac srcdir="${basedir}" destdir="${basedir}/build/classes" includeAntRuntime="false"/>
</target>
<target name="jar">
<mkdir dir="build/jar"/>
<jar destfile="build/jar/HelloWorld.jar" basedir="build/classes">
<manifest>
<attribute name="Main-Class" value="test.HelloWorld"/>
</manifest>
</jar>
</target>
<target name="run">
<java jar="build/jar/HelloWorld.jar" fork="true"/>
</target>
</project>
run as ant build结果为
Buildfile: G:\workspace\itProject\src\build.xml
clean:
clean:
compile:
[mkdir] Created dir: G:\workspace\itProject\src\build\classes
[javac] Compiling 1 source file to G:\workspace\itProject\src\build\classes
jar:
[mkdir] Created dir: G:\workspace\itProject\src\build\jar
[jar] Building jar: G:\workspace\itProject\src\build\jar\HelloWorld.jar
run:
[java] HelloWorld
BUILD SUCCESSFUL
Total time: 1 second
表示build成功
以上是web项目当中，可以直接build，但是我发现在java普通项目中需要分开运行，就是先clean compile再jar run
