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.
