即使目录存在，nant directory :: exists也会返回false(nant directory::exists returns false even though directory exists)

我正在尝试检查目录是否作为NAnt脚本的一部分存在并获得误报。 这是脚本片段：

<echo message="${backup.dir} --> ${directory::exists('${backup.dir}')}"/>

这是输出：

[echo] D:\D\RTC\backup\20110223 --> False

除了该目录存在。

作为一个侧面说明，如果我跑..

<echo message="${backup.dir} --> ${directory::get-creation-time('${backup.dir}')}"/>

我收到以下错误：

Expression: ${backup.dir} --> ${directory::get-creation-time('${backup.dir}')} ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Could not find a part of the path "D:\D\RTC\${backup.dir}".

如果我运行..

<echo message="Directory Name --> ${path::get-directory-name('${backup.dir}')}"/>

我明白了

[echo] Directory Name -->

总而言之，我现在很困惑..有什么想法吗？

I'm trying to check for if a directory exists as part of a NAnt script and getting a false negative. Here is the script fragment:

<echo message="${backup.dir} --> ${directory::exists('${backup.dir}')}"/>

Here is the output:

[echo] D:\D\RTC\backup\20110223 --> False

Except the directory exists.

As a side note if I run..

<echo message="${backup.dir} --> ${directory::get-creation-time('${backup.dir}')}"/>

I get the following error:

Expression: ${backup.dir} --> ${directory::get-creation-time('${backup.dir}')} ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Could not find a part of the path "D:\D\RTC\${backup.dir}".

AND if I run..

<echo message="Directory Name --> ${path::get-directory-name('${backup.dir}')}"/>

I get

[echo] Directory Name -->

All in all I'm very confused right now.. Any thoughts?

您不能以嵌套方式使用${} ：

<echo message="${backup.dir} --> ${directory::exists(backup.dir)}"/>

You must not use ${} in a nested way:

<echo message="${backup.dir} --> ${directory::exists(backup.dir)}"/>
