Subject: Re: Exception when using package resolver

It's a bug, but you can safely ignore it. This is occurring while the packager 
resolver is attempting to delete the temporary build directory it uses.

However, the bug can only occur (according to the Javadocs) if an I/O error has 
occurred while attempting to delete some file(s). This probably includes 
problems like wrong permissions, etc., so you might investigate what might 
prevent ivy from being allowed to delete files.

The attached patch should fix the exception (but not the underlying problem). If 
you have a chance please file a bug and reference this patch.
