一，为减小 build.xml 文件的大小，使用XML实体
把属性的设置都放一个 XML 文件中
props.xml 文件
property name ="build.dir" value ="build" />
然后在 build.xml 文件中加入如下
DOCTYPE project [ ]>
二，将多个目录的源文件编译到一个地方
javac destdir ="build/classes">
src path ="src1"/>
src path ="src2"/>
javac >
三，保存构建时的信息
project default ="init">
target name ="init"> target >
property environment ="env" />
property name ="env.COMPUTERNAME" value ="${env.HOSTNAME}" />
propertyfile comment ="Build Information" file ="./buildinfo.properties">
entry key ="build.host" value ="${env.COMPUTERNAME}" />
entry key ="build.user.name" value ="${user.name}" />
entry key ="build.os.name" value ="${os.name}" />
propertyfile >
project >
四，去除属性文件的注释
属性文件：
# 这里是注释，会给过滤掉
build.dir = build
build 文件：
copy file ="props.properties" todir ="sample">
filterchain >
striplinecomments >
comment value ="#" />
striplinecomments >
filterchain >
copy >
五，两个花俏的功能
1. 声音提示
project name ="Sound" default ="all">
property file ="build.properties" />
target name ="init">
sound >
success source ="${sound.dir}/success.wav" duration ="500" />
fail source ="${sound.dir}/fail.wav" loops ="2" />
sound >
target >
target name ="fail" depends ="init">
fail />
target >
target name ="success" depends ="init" />
target name ="all" depends ="success" />
project >
2. 进度条提示
project name ="splash" default ="init">
target name ="init">
splash imageurl ="http://java.chinaitlab.com/UploadFiles_8734/200610/20061021103415601.gif" showduration ="5000" />
sleep seconds ="1" />
sleep seconds ="1" />
sleep seconds ="1" />
sleep seconds ="1" />
sleep seconds ="1" />
sleep seconds ="1" />
