Ant教程

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:Softwareant1.9.7   //ant根目录

在PATH后添加　

;%ANT_HOME%in            //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="itPackage" basedir="." default="main">

    <property name="src.dir"     value="src"/>
    <property name="build.dir"   value="build"/>
    <property name="classes.dir" value="${build.dir}/classes"/>
    <property name="jar.dir"     value="${build.dir}/jar"/>

    <property name="main-class"  value="test.HelloWorld"/>

    <target name="clean">
        <delete dir="${build.dir}"/>
    </target>

    <target name="compile">
        <mkdir dir="${classes.dir}"/>
        <javac srcdir="${basedir}" destdir="${classes.dir}" includeAntRuntime="false"/>
    </target>

    <target name="jar" depends="compile">
        <mkdir dir="${jar.dir}"/>
        <jar destfile="${jar.dir}/${ant.project.name}.jar" basedir="${classes.dir}">
            <manifest>
                <attribute name="Main-Class" value="${main-class}"/>
            </manifest>
        </jar>
    </target>

    <target name="run" depends="jar">
        <java jar="${jar.dir}/${ant.project.name}.jar" fork="true"/>
    </target>

    <target name="clean-build" depends="clean,jar"/>

    <target name="main" depends="clean,run"/>

</project>

　　

run as ant build结果为

Buildfile: G:workspaceitProjectsrcuild.xml

表示build成功

注意：javaEE工程是run之后不会clean，而java工程则run完之后会clean
