C:\software\apache-maven-3.0.3\conf\settings.xml I have enabled proxies here as:

….   <proxies>     <!-- proxy      | Specification for one proxy, to be used in connecting to the network.      |-->     <proxy>       <id>optional</id>       <active>true</active>       <protocol>http</protocol>             <host>www.BT.co.uk</host>       <port>80</port>       <nonProxyHosts>localhost|google.com</nonProxyHosts>     </proxy>    </proxies> 

What is the problem I am facing here? Why it is not downloading?

Answer 1

Found solution:

Solution #1:

issue was with proxy in settings.xml file:

<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.
