我可以在Ant复制任务操作系统的具体情况？ [英] Can I make the Ant copy task OS-specific?

问题描述

我有执行使用复制任务复制操作的Ant脚本。它是为Windows编写的，并具有硬codeD C：\\路径为todir的说法。我看到了'EXEC'任务都有一个操作系统的说法，有没有类似的方式进行分支基于OS的副本？

I have an Ant script that performs a copy operation using the 'copy' task. It was written for Windows, and has a hardcoded C:\ path as the 'todir' argument. I see the 'exec' task has an OS argument, is there a similar way to branch a copy based on OS?

推荐答案

我会建议投入属性的路径，然后根据当前的操作系统有条件设置属性。

I would recommend putting the path in a property, then setting the property conditionally based on the current OS.

<condition property="foo.path" value="C:\Foo\Dir">
   <os family="windows"/>
</condition>
<condition property="foo.path" value="/home/foo/dir">
   <os family="unix"/>
</condition>

<fail unless="foo.path">No foo.path set for this OS!</fail>

作为一个附带好处，一旦它在一个属性，你可以覆盖它，而无需编辑Ant脚本。

As a side benefit, once it is in a property you can override it without editing the Ant script.
