ant生成war包的简单实现

按网上的操作，实现一下。

build.xml:

<?xml version="1.0" ?>
<project  name ="antwebproject"   default ="war" basedir =".">
  <property  name ="classes"  value ="build/classes"/>
     <property  name ="build" value ="build"/>
     <property  name ="lib" value ="WebRoot/WEB-INF/lib"/>
     <!--  删除build 路径-->
     <target  name ="clean">
        <delete  dir ="build"/>
     </target>

     <!--  建立build/classes 路径，并编译class 文件到build/classes 路径下-->
     <target  name ="compile"  depends ="clean">
        <mkdir  dir ="${classes}"/>

        <javac  srcdir ="src"  destdir ="${classes}"/>
     </target>

     <!--  打war 包-->
     <target  name ="war"  depends ="compile">
       <war  destfile ="${build}/antwebproject.war"  webxml ="WebRoot/WEB-INF/web.xml">
            <!--  拷贝WebRoot 下除了WEB-INF 和META-INF 的两个文件夹-->
            <fileset  dir ="WebRoot"  includes ="**/*.jsp"/>

            <!--  拷贝lib 目录下的jar 包-->
            <lib  dir ="${lib}"/>
            <!--  拷贝build/classes 下的class 文件-->
            <classes dir ="${classes}"/>
        </war>
     </target>
</project>

定义的目录结构：
