i have added proxy also .

<proxy>
  <id>myproxy</id>
  <active>true</active>
  <protocol>http</protocol>
  <host>proxy.bbh.com</host>
  <port>8080</port>
  <username>proxyuser</username>
  <password>somepassword</password>
  <nonProxyHosts>*.google.com|ibiblio.org</nonProxyHosts>
</proxy>

It just seems that you can't connect to repo1. As you added ibiblio.org in your nonProxyHosts list I think that adding *.maven.org should work.
