NullPointerException on empty relocation pattern (default package)
------------------------------------------------------------------
Key: MSHADE-94
URL: http://jira.codehaus.org/browse/MSHADE-94
Project: Maven 2.x Shade Plugin
Issue Type: Bug
Affects Versions: 1.4
Reporter: J@ck
I need a few classes from a 3rd party jar that are declared in the default
package. Since usage of the default package should be avoided, I try to
relocate the classes to a named package:
{code:title=pom.xml}
...
<relocation>
<pattern />
<shadedPattern>org.example.foo.bar</shadedPattern>
</relocation>
{code}
The Shade Plugin crashes with a NPE:
{code:title=Stacktrace}
