ant生成war包的简单实现

<?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>
