一、首先定义一些变量，如下，个人感觉有点类似makefile的写法
#==================== File and Directory Names ======================== app.name=AntDemo app.version=0.1 source.home=./src lib.home=./WebContent/WEB-INF/lib lib.external=./lib_external webapp.home=./WebContent build.home=./build dist.home=./dist #==================== Compilation Control Options ===================== compile.debug=true compile.deprecation=false compile.optimize=true
二、然后写几个target
一般就clean，init，Compile，Build，Archive，具体如下
<?xml version="1.0"?> <!-- ====================================================================== Date: June 2015 Project: Ant Demo Author: Peter Chen ====================================================================== --> <project name="AntDemo" default="archive" basedir="."> <description> a project of using ant </description> <property file="build.properties"/> <!-- ==================== Clean Target ==================================== --> <!-- 删除之前工程构建时产生的临时文件 --> <target name="clean" description="Delete old directories and files"> <delete dir="${dist.home}"/> <delete dir="${build.home}"/> <delete > <fileset dir="${source.home}" includes="**/*.class"/> </delete> </target> <!-- ==================== Init Target ================================== --> <!-- 新建build文件夹 --> <target name="init" depends="clean" description="Create build directory"> <mkdir dir="${build.home}" /> </target> <!-- ==================== Compile Target ================================== --> <!-- 编译源代码，将编译生成的class文件copy到${build.home}/WEB-INF/classes目录下 --> <target name="compile" depends="init" description="Compile Java sources"> <mkdir dir="${build.home}/WEB-INF/classes" /> <javac srcdir="${source.home}" destdir="${build.home}/WEB-INF/classes" debug="${compile.debug}" deprecation="${compile.deprecation}" optimize="${compile.optimize}" source="1.7" target="1.7" includeantruntime="on"> <classpath> <path> <fileset dir="${lib.home}" /> <fileset dir="${lib.external}" /> </path> </classpath> </javac> </target> <!-- ==================== Build Target ================================== --> <!-- 把非class文件拷贝到build目录下 --> <target name="build" depends="compile" description="Copies all non Java classes to build directoy"> <copy todir="${build.home}"> <fileset dir="${webapp.home}" excludes="SVN,**/*.class" /> </copy> <copy todir="${build.home}/WEB-INF/classes"> <fileset dir="${source.home}" excludes="SVN,**/*.java" /> </copy> </target> <!-- ==================== Archive Target ================================== --> <!-- 打包成war文件 --> <target name="archive" depends="build" description="Create binary archive of all files in dist.home"> <!-- Create war directory --> <mkdir dir="${dist.home}" /> <!-- Create application WAR file --> <jar jarfile="${dist.home}/${app.name}.war" basedir="${build.home}" /> </target> </project>
三、最后直接运行target即可

有兴趣的可以下载下来看看，一个基于struts2的web工程，使用ant自动编译打包成war。
