Answer 1

If you are behind a proxy, you need to configure Maven to use this proxy. To do so, edit or create the file ${user.home}/.m2/settings.xml and add the following snippet to it:

<settings>
  .
  .
  <proxies>
   <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>
  </proxies>
  .
  .
</settings>

One thing you can try if you're missing a particular resource, is to browse the repository directly, e.g. http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-resources-plugin/2.3/

In this case it looks like the 'maven-resources-plugin' is present. If you are behind a firewall, it might be worth editing your /conf/settings.xml to specify proxy details.

Another thing you can try is to execute the mvn command with -U. This should force an update of resources not in your local repository.
