Benjamin Bentmann commented on MWAR-190:
----------------------------------------
Trenton, you might be confusing the Maven version (2.0.10, 2.1.0) with the WAR
Plugin version (2.1-beta-1). This issue originates from the plugin, not the
Maven core, so you shouldn't need to change your Maven version (though 2.1.0
should be superior compared to 2.0.10) but just update your POM to declare a
recent version of the maven-war-plugin.
