Subject Re: How to set a new property based on value of another property in Ant ?
Date Tue, 29 Jan 2008 13:05:51 GMT
Thanks Jan, I created my own task and integrated into my build
process, but initial reason to ask this to the group was that if Ant
has a standard way to achieve this then why I should create seperate
task, at last for my own task I have to maintain and document the
same, which would not have been the case in case of standard Ant task
;-)

Thanks again for your help.

Regards,
Ravi.
