Maven is not working,failed to reterving

This is the common problem you would see in corporate level
It is because of the proxy problem there are few ways to
sort of the proble...look in those
Solution #1:

issue was with proxy in settings.xml file:check your user/.m2/setting.xml

<host>webproxy</host>
to get host goto IE->tools->connection->LAN settings->advanced->http.

=====
Solution #2:

if auto configured proxy is given: then

1> open IE(or any browser)

2> get the url address from your browser through IE->Tools->internet option->connections->LAN Settings->
get address and give in url eg: as http://autocache.abc.com/ and enter, a file will be downloaded with .pac format,
save to desktop

3> open .pac file in textpad, identify PROXY:

In your editor, it will come something like:

   return "PROXY web-proxy.ind.abc.com:8080; PROXY proxy.sgp.abc.com:8080";
4> go to Maven settings.xml and enter as:

<proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>        
      <host>web-proxy.ind.abc.com</host>
      <port>8080</port>        
</proxy>
5> run mvn:install through command prompt or run through eclipse.

=====

Solution #3:
For any other issues delete maven local repository and run mvn:install again.
