Create a zip file using maven

I'm trying to use the assembly plugin in order to create a zip file for a specific module of a multi-module Maven project. This module cointains only a bunch of xml and xsl files that needs to be packaged as a zip file (the folder's structure is saved under src/main/resources).

So I created the pom below:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <parent>
<groupId>foo.bar</groupId>
<artifactId>myserver</artifactId>
<version>${myserver.version}</version>
  </parent>
  <modelVersion>4.0.0</modelVersion>
  <groupId>foo.bar</groupId>
  <artifactId>zip-sample</artifactId>
  <name>Sample zip</name>
  <version>${myserver.version}</version>
  <build>
<plugins>
  <plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.4.1</version>
    <executions>
      <execution>
    <configuration>
      <descriptorRefs>
        <descriptorRef>bin</descriptorRef>
      </descriptorRefs>
    </configuration>
    <id>create-distribution</id>
    <phase>package</phase>
    <goals>
      <goal>single</goal>
    </goals>
      </execution>
    </executions>
  </plugin>
</plugins>
  </build>
</project>

but I get the error:

I tried to change the assembly plugin version, but I always the "Not a v4.0.0 POM" error even if the pom seems ok.

Maven's version used:

$ mvn -v
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.6.0_20
Java home: /usr/lib/jvm/jdk1.6.0_20/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux" version: "3.11.0-12-generic" arch: "amd64" Family: "unix"

Could it be a problem in the plugin definition inside the pom.xml?

is it possible that particular POM file is corrupt or mangled? Can you look at the contents of: /home/gundam/.m2/repository/org/apache/maven/plugins/maven-assembly-plugin/2.3/maven-assembly-plugin-2.3.pom

See here What does this mean: Not a v4.0.0 POM. for project org.codehaus.mojo:rpm-maven-plugin where someone has a similar issue.
