Please add information, like error log, and what you really need !

As a beggining, does you archiva repository needs credentials. If true, consider adding them like this :

  <!-- servers
   | This is a list of authentication profiles, keyed by the server-id used within the system.
   | Authentication profiles can be used whenever maven must make a connection to a remote server.
   |-->
  <servers>
        <server>
            <id>internal</id>
            <username>username</username>
            <password>password</password>
        </server>
  </servers>
