Chandra,
MyEclipse doesn’t currently use Ant for handling building of projects and there isn’t support for exporting one, although it is an open enhancement we hope to add to a future release.
The primary challenge for us is that Ant doesn’t support some of the features that MyEclipse offers for building/deploying applications, so we would need to figure out either a) how to work around them or b) where to draw the line when generating an Ant script.
