ant的一些偏门技巧

一为减小 buildxml 文件的大小使用XML实体

把属性的设置都放一个XML文件中

propsxml 文件

<property name=builddir value=build />

然后在 buildxml 文件中加入如下

<!DOCTYPE project [<!ENTITY properties SYSTEM file:propsxml>]>

二将多个目录的源文件编译到一个地方

<javac destdir=build/classes>

<src path=src/>

<src path=src/>

</javac>

三保存构建时的信息

<project default=init>

<target name=init></target>

<property environment=env />

<property name=envCOMPUTERNAME value=${envHOSTNAME} />

<propertyfile comment=Build Information file=/buildinfoproperties>

<entry key=buildhost value=${envCOMPUTERNAME} />

<entry key=buildusername value=${username} />

<entry key=buildosname value=${osname} />

</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

builddir = build

build文件

<copy file=propsproperties todir=sample>

<filterchain>

<striplinecomments>

<comment value=# />

</striplinecomments>

</filterchain>

</copy>

五两个花俏的功能

声音提示

<project name=Sound default=all>

<property file=buildproperties />

<target name=init>

<sound>

<success source=${sounddir}/successwav duration= />

<fail source=${sounddir}/failwav loops= />

</sound>

</target>

<target name=fail depends=init>

<fail />

</target>

<target name=success depends=init />

<target name=all depends=success />

</project>

进度条提示

<project name=splash default=init>

<target name=init>

<splash imageurl=_//gif showduration= />

<sleep seconds= />

<sleep seconds= />

<sleep seconds= />

<sleep seconds= />

<sleep seconds= />

<sleep seconds= />

</target>

</project>
