Possible regression using web resource filtering

Fri, 03 Jul 2009 00:34:54 -0700 

Hello,

I just added filtering to a web project as follows:

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-war-plugin</artifactId>
   <configuration>
       <webResources>
           <webResource>
               <directory>src/main/webapp/WEB-INF</directory>
               <includes>
                   <include>web.xml</include>
               </includes>
               <targetPath>WEB-INF</targetPath>
               <filtering>true</filtering>
           </webResource>
       </webResources>
   </configuration>
</plugin>
The version of the War Plugin is 2.1-beta-1. This works as expected with Maven 2.0.10. Using Maven 2.1.0 or Maven 2.2.0, I get the error below. Is this a regression or something the War Plugin needs to address? There is no problem without the filtering.
