Help with exec

["Ron J. Green, Jr." <rg...@austin.rr.com>]

Hello,

I just started using ANT this week and am rapidly growing to rely upon it.
However, I'm having trouble with the "exec" task. On my Windows 2000 machine
when I add the os="windows" attribute, it fails to execute. But when I echo
the "os" property it prints "windows". Example below.

  <target name="test">
    <echo message="${os}" />
    <exec executable="dir" os="windows"/>
  </target>

Thanks in advance for any assistance.

Ron

Does it work if you use a capital W in Windows (don't have Windows
here to check). Looking at the code it seems to be case sensitive.

You're right, I picked a bad example. Your example works fine as long as I
leave out os="windows". If I include it, however, doesn't run on my Windows
2000 machine.

Is this a known problem. I checked the FAQ and didn't see it mentioned.

Thanks again,
Ron

I may be wrong (as I don't have the slightest understanding of Windows
8-), but ISTR dir is not an executable but a shell builtin.

Does

<exec executable="cmd" os="windows">
  <arg line="/c dir" />
</exec>

or something similar work?
