Question: I want to delete directory from my maven project when i am running mvn eclipse:clean

This is what I have added in my pom.xml under suite tag. But when i run mvn eclipse:clean it successfully deletes .project and .setting files but not my Report directory.

<build>
 <pluginManagement>
  <plugins>
   <plugin>
    <artifactId>maven-clean-plugin</artifactId>
    <version>2.4.1</version>
    <configuration>
     <filesets>
        <fileset>
            <directory>Reports</directory>
            <includes>
                <include>**</include>
            </includes>
            <followSymlinks>false</followSymlinks>
        </fileset>
     </filesets>
    </configuration>
   </plugin>
  <plugins>
 <pluginManagement>
</build>

Please suggest if I am putting the plugin tags at wrong places.
