If you access the Internet through a proxy, you will need to configure Maven to download dependencies through this proxy, following the `Configuring a proxy`__ instructions at the Maven page.

Basically, this consists of including the corresponding configuration in the *.m2/settings.xml* file:: 

    

    
    
       ...

        
            
                true
                http
                proxy.somewhere.com
                8080
                proxyuser
                somepassword
                www.google.com|*.somewhere.com
