maven: Error transferring file: Connection refused: connect

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.

go through maven-in-5-min-not-working

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.
