Iain Coulter commented on IVY-357:
----------------------------------

I've created a partial fix for this.   This doesn't currently use an ant  task but instead modifies the retrieve code to handle a special "unzip" artifact type.   When a file of this type is encountered it is unzipped to the specified location instead of copying the file, this also follows for dependencies which are also of type unzip.

This is a patch from the 1.4.1 code base.

>                       Message.verbose("\t\tto and unzipping"+destFile.getParent());
>                       ZipUtil.unzip(archive,new File(destFile.getParent()), false);
>                        
>                     }
>                     else if (!_checkUpToDate || !upToDate(archive, destFile)) {

Also attached to this issue is ZipUtil.java which implements ZipUtil class referenced in the above code

> The following is from one message in that thread:
> A resolver that wraps another resolver but also can invoke an ant build script for a dependency if an Ant script is available. The build script would be invoked at most once per build for each dependency. Something like this:
> 1. Need latest version for dependency "A".
> 2. Is there an Ant script for dependency "A"?
> - If yes: invoke script if it has not yet been invoked for this build
> 3. Call wrapped resolver to actually retrieve the published artifact(s).
> Note: I don't think this would apply if a specific version is being referenced - only if something like "test.integration" is being referenced?
> The trick then would be to figure out if a) a dependency has an Ant build script, b) where the script is located, and c) what target to call on the script.
> Then, all I do is tell Ivy to resolve in my main Ant build and it will do the rest to ensure that all my dependencies are up-to-date.
