NPE during packaging.
---------------------
Key: MWAR-169
URL: http://jira.codehaus.org/browse/MWAR-169
Project: Maven 2.x War Plugin
Issue Type: Bug
Affects Versions: 2.1-alpha-2
Reporter: Maarten Billemont
The following NPE happens when I run maven from the parent in a multi-module
project; though it does not occur when I run mvn clean install from within the
module itself.
