我可以使 Ant 复制任务特定于操作系统吗? [英] Can I make the Ant copy task OS-specific?

问题描述

我有一个 Ant 脚本，它使用 'copy' 任务执行复制操作.它是为 Windows 编写的，并且有一个硬编码的 C:\ 路径作为 'todir' 参数.我看到 'exec' 任务有一个 OS 参数，是否有类似的方法可以基于 OS 分支副本?

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

我建议将路径放在一个属性中，然后根据当前操作系统有条件地设置该属性.

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>

作为附带的好处，一旦它位于属性中，您就可以在不编辑 Ant 脚本的情况下覆盖它.

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