You may want to look at the FilterChains and FilterReaders elements to 'select' which lines of the original properties file to copy and then merely append the new line.
Maybe use the <lineContainsRegExp> element to 'select' all the lines EXCEPT the one(s) you want to change and copy the 'selected' lines to a temp file and then merely <echo> the new property value into the temp file and the copy the temp to the final name/location. Alternately you can create your own FilterReader...rather simple but requires a little JAVA coding experience Hope that helps, Ninju ----- Original Message ---- From: jm <[EMAIL PROTECTED]> To: Ant Users List <user@ant.apache.org> Sent: Tuesday, December 19, 2006 8:07:05 AM Subject: Re: set a property in a .properties file Peter, thanks for pointing that out, I'll check that if it works that would be perfect.
