Description

A NullPointerException is thrown, if I try to resolve a dependency after I cleared the cache.

Steps to reproduce:

1. create a ivysettings.xml with a chain including a ibiblio and an updatesite as resolver.
2. create a dependency to a artifact that can be found with the ibiblio resolver.
3. call ivy retrieve

actual result:

• no dependency is resolved and retrieved and a NullPointerException is thrown

expected result:

• dependency is resolved and retrieved from ibiblio

See also the attached patch and test case.
