Ant Command Line help: iisvdir

Question

I'm trying to execute iisvdir from an ant script to clean and create a virtual directory before I compile my .net app in Visual Studio. I am running into a couple of strange errors one one build server, but another is running the script without any problem.

    <exec dir="${SYSTEM32}" executable="cscript" failonerror="true">
        <arg line='iisvdir.vbs /create "Default Web Site" ${RS_VIRTUAL_DIR} "${env.WORKSPACE}"'/>
    </exec>

Results in:

     [exec] Microsoft (R) Windows Script Host Version 5.6
  [exec] Copyright (C) Microsoft Corporation 1996-2001. All rights reserved.
  [exec]
  [exec] Input Error: Can not find script file "c:\windows\system32\iisvdir.vbs".

And then

    <exec dir="${SYSTEM32}" executable="cmd" failonerror="true">
        <arg line='cscript iisvdir.vbs /create "Default Web Site" ${RS_VIRTUAL_DIR} "${env.WORKSPACE}"'/>
    </exec>

Results in

 [exec] 'reate' is not recognized as an internal or external command,
 [exec] operable program or batch file.

Can someone help me figure out what might be wrong?

Answer 1

Hi, I don't know if it's the cause of your problems but I notice that you are using a single quote (') for <arg line='. All the examples I've seen use a double quote (") I know you are enclosing items with spaces in double quotes so it may be necessary to escape them out? Perhaps moving the code into a batch file which you can test before running via Ant?

Not sure if this will help but could point you in the right direction.

1. Is iisvdir.vbs where you say it is?
2. To get CMD.EXE to run a command, you need to use the /C switch.

For example:

cmd.exe echo Hello

...ignores the parameters and runs another interactive command prompt as a subshell.

cmd.exe /c echo Hello

...runs the "echo Hello" statement and returns immediately. Note: You can use /K if you want cmd.exe to continue running interactively after running the statement (not usually a good idea in a build script).

Your command:

cmd.exe cscript iisvdir.vbs /create etc.

...is getting parsed as if you'd really said:

cmd.exe /c reat etc.

This is because cmd.exe has (as with most MS command line tools) freaky command line parsing.

Update: Is this a 64-bit OS? If Ant is a 32-bit task, then it'll actually (silently) be looking in C:\Windows\SysWOW64 for cscript.exe and iisvdir.vbs. Are they there? If not, you should use C:\Windows\SysNative. In a 32-bit task, this is aliased to the real C:\Windows\System32 directory.
