Maven deploy failed?

Hi, I created new maven artifact using archiva, in order to share updated jar projects with my team. when I try to deploy the project I got this fail:

this what I added to pom.xml file:

    <repository>
      <id>stmaven</id>
      <name>stmaven</name>
      <url>http://stmaven:8888</url>
    </repository>


 what added to setting.xml file:
<servers>

    <server>
      <id>VirtualMachineName</id>
      <username>user</username>
      <password>pass</password>
    </server>
    <!---->


  </servers>


  <mirrors>

      <name>maven archiva Mycompany</name>
      <url>http://VirtualMachineName:8888/#browse/**groupId**</url>

Note : I'm very new with creating and maintain maven repository.

Thank you
