Maarten Billemont commented on MWAR-169:
----------------------------------------

Commenting out these options in the maven-war-plugin's configuration section avoids this problem:
                    <packagingExcludes>WEB-INF/lib/*</packagingExcludes>
                    <filteringDeploymentDescriptors>true</filteringDeploymentDescriptors>


> NPE during packaging.
