I have a war-project that contains two webResources:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <webResources>
            <resource>
                <directory>WebappWork</directory>
                <excludes>
                    <exclude>WEB-INF/web.xml</exclude>
                    <exclude>WEB-INF/lib/*</exclude>
                </excludes>
            </resource>
            <resource>
                <directory>src/main/webapp</directory>
            </resource>
        </webResources>
    </configuration>
</plugin>

Only the first resource is displayed in the Web Pages node.
