----------------------------------------------------------------------------
Key: IVY-774
URL: https://issues.apache.org/jira/browse/IVY-774
Project: Ivy
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0-beta-2
Environment: Windows/JDK1.5
Reporter: Carlton Brown
Priority: Minor
Fix For: unspecified
If a resolver references a cache that is not already defined, an NPE occurs.
Such as:
<ibiblio cache="MyCache">
...
</ibiblio>
If MyCache is not defined in <caches> then you get something like this:
