蚂蚁条件如果macrodef内 [英] ant conditional if within a macrodef

问题描述

在蚂蚁，我有一个macrodef。

Within ant, i have a macrodef.

假设我已经使用这个macrodef，并且有一个项目里面说macrodef，我要运行当且仅当该属性special.property存在，并且是真实的，我该怎么办？

Assuming i have to use this macrodef, and there is a item inside said macrodef that i want to run iff the property special.property exists and is true, what do i do?

我目前有

<macrodef name="someName">
    <sequential>
        <someMacroDefThatSetsTheProerty  />
        <some:thingHereThatDependsOn if="special.property" />
    <sequential>
</macrodef>

不工作 - 在一些：thingHereThatDependsOn可是没有如果属性，我不能添加一到它

Which doesn't work - the some:thingHereThatDependsOn doesnt have an "if" attribute, and I cannot add one to it.

antcontrib不可用。

antcontrib is not available.

通过一个目标，我可以给目标一个如果，我可以用macrodef做什么？

With a target I can give the target an "if", what can I do with a macrodef?

推荐答案

这是唯一可能的，如果ANTthingHereThatDependsOn任务支持的如果属性。

This is only possible if the ANT "thingHereThatDependsOn" task supports an "if" attribute.

如上所述，在ANT条件执行，通常仅适用于目标

As stated above, conditional execution in ANT, normally, only applies to targets.

<target name="doSomething" if="allowed.to.do.something">
   ..
   ..
</target>

<target name="doSomethingElse" unless="allowed.to.do.something">
   ..
   ..
</target>

<target name="go" depends="doSomething,doSomethingElse"/>
