<uptodate> and <dependset> are both useful, but the best IMHO is Ant-Contrib's <outofdate>. Note though that the above is a generic statement. In your particular case of using <exec>, <apply> would be the best choice, as it can do timestamping automatically. One reason I wouldn't use <apply> but <ac:outofdate> instead is that is not readily apparent that <apply> does the timestamping, and many people don't know about this feature, whereas it's much more obvious with <outofdate>. I hope this is not too late to be useful ;-) --DD --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
