ClasscastException when turning filtering on the web resources
--------------------------------------------------------------

                 Key: MWAR-134
                 URL: http://jira.codehaus.org/browse/MWAR-134
             Project: Maven 2.x War Plugin
          Issue Type: Bug
    Affects Versions: 2.0.2
         Environment: Maven 2.0.8, Win XP
            Reporter: Ludovic Claude


Hello,

I have configured the maven-war-plugin to filter my files in src/main/webapp, in particular
web.xml. 

<plugin>
		<groupId>org.apache.maven.plugins</groupId>
		<artifactId>maven-war-plugin</artifactId>
		<configuration>
			<archive>
				<addMavenDescriptor>
					false
				</addMavenDescriptor>
			</archive>
			<webResources>
				<resource>
					<filtering>true</filtering>
					<directory>
						src/main/webapp
					</directory>
					<includes>
						<include>**/*</include>
					</includes>
				</resource>
			</webResources>
		</configuration>
	</plugin>

But when I run Maven, I get the following error: 

[INFO] Copy webapp webResources to [...]\client-framework-webapp-0.2-SNAPSHOT
[INFO] ------------------------------------------------------------------------
[ERROR] FATAL ERROR
