Subject [jira] Created: (MWAR-169) NPE during packaging.
Date Fri, 05 Sep 2008 13:50:58 GMT
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.
