"choice" command not found - Problem with ANT 1.7.0 ??

[Ka...@gi-de.com]

Hello,

we have some larger and older build scripts which are running properly 
with ANT 1.6.5. 
Our Operating system is  Windows XP SP2 and the scripts are started from a 
batch with  "%ANT_HOME%\bin\ant ...".

If i switch to ANT 1.7.0 via the ANT_HOME variable i got the following 
error message after the ant-call:
       "Der Befehl "choice" ist entweder falsch geschrieben oder konnte 
nicht gefunden werden"
This is the german version of the standard message in a command shell for 
a unknown command.

This is very strange because ...
   * We don't use the "choice" command anywhere in our batches (we know it 
is NOT a standard XP command).
   * We don't use the "input" task anywhere in our scripts (may be it uses 
internally the 'choice' ??)
   * The ant scripts itself works properly, the message appears if the 
script already has finished and aborts the batch
   * Some newer scripts written within eclipse using the PDE build process 
are running properly if started via batch

It would be great if anybody has an explanation / solution for this 
behaviour.

Mit freundlichen Grüßen / kind regards
