hi all - a bit of clumsy situation but for the moment we cannot migrate to more straight-forward project layout.

We have a project called myServices and it has 2 source folders (yes, I know, but that's the way it is for now) - I'm trying to make build process a bit more flexible so we now have a property called artifact.names that will be parsed by generic build.xml and based on name, it will call either jar or war task, eg. myService-war will create a WAR file with the following zipfilesets included there: myService-war-classes, myService-war-web-inf, myService-war-meta-inf. I want to add a bit more flexibility, and allow having additional zipfilesets, eg. myService-war-etc-1,2 etc - so these will be picked up by the package target automatically. I cannot use "if" inside war target, and also ${ant.refid:myService-war-classes} property is not resolved, so I'm kind of stuck at the moment with my options - how do I dynamically include a zipfileset into a WAR? You can refer to fileset by id, but it MUST be defined then, eg. you can't have it optional on project level. Thank you. Some build.xml snippets:

    <for list="${artifact.names}" param="artifact">
