Answer 1

Are you working with a proxy? If so, you can check your proxy configuration in your %MAVEN_HOME%/conf/settings.xml

 <proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <username></username>
  <password></password>
  <host></host>
  <port></port>
  <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>

It´s seem that you are not able to connect to maven repository
