Apache Maven Error : Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom: 2.5 to central

I am new at this. I am working on apache maven. I am working behind a proxy server. Every time, I try to build maven project. It gives me this error. I also changed proxy settings in settings.xml file. But It is not working. It keeps giving me same problem. Build Failure. I have searched for answer on net. But I could not find it. I am trying to integrate a CAS into my web applications and sites. If anybody also has suggestion for that please help me. Edit:- pom.xml file:-

  <proxies>
  <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |-->
    <proxy>
      <id>myproxy</id>
      <active>true</active>
      <protocol>http</protocol>
     <username>username</username>
      <password>pass</password>
      <host>companyhost</host>
      <port>8080</port>
     <!-- <nonProxyHosts>local.net|some.host.com</nonProxyHosts>-->
    </proxy>

  </proxies>

error:-

I think you need to set up a maven proxy in your settings.xml properly.

Have a look (for example) in your web browser and see how it is set up.

From the documentation on Configuring a proxy:

<proxy>
  <active>true</active>
  <protocol>http</protocol>
  <host>proxy.somewhere.com</host>
  <port>8080</port>
  <username>proxyuser</username>
  <password>somepassword</password>
  <nonProxyHosts>www.google.com|*.somewhere.com</nonProxyHosts>
</proxy>

Better ask your colleague for working proxy. No company will block this thing
