maven: Error transferring file: Connection refused: connect - maven

Question

I am working in a network environment.
my network ip address for internet is:
IE->tools->internet options->connections->LAN settings->Use Automatic configuration script(enabled): Address: http://autocache.abc.com/
port address is not specified in IE settings.
when i do ping autocache.abc.com it gives following ip address: 16.234.18.243
in settings.xml file i have enabled entry for proxy as:
<proxy>
<id>genproxy</id>
<active>true</active>
<protocol>http</protocol>
<host>autocache.abc.com</host>
</proxy>
Nothing is specified at Ie host ie: IE->tools->connection->LAN settings->advanced->http shows empty
if i run mvn install getting following error:

If I run mvn install without network connection ie at my private internet connection, it is working fine and only problem is with network proxy.
I strongly feel it is host issue, if I give host as 16.234.18.243 instead of autocache.abc.com, still gives same error.
I tried to create new local repository( ie deleted existing directory), but still same issue.

Answer 1

1> open IE(or any browser),
2> give url as http://autocache.abc.com/ ( you have given above) 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.

Answer 2

The URL you specified most likely contains a Proxy auto-config file . You need to download it and see what the proxy settings specified in it are.
For instance, the file contents
function FindProxyForURL(url, host)
{
return "PROXY proxy.example.com:8080; DIRECT";
}
indicates that you should use the proxy server proxy.example.com on port 8080.
For a more elaborate example, see How to configure Maven behind an auto configured proxy .
