ClasscastException when turning filtering on the web resources

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
