Eclipse IDE

Right! The same thing you did in home didn’t work for your office setup (though you couldn’t not blame that it could be due to your office PC setup not being blazingly faster than your home PC, but that is not the “root cause” 90% of the time =p)

Chances are, when you are in the office, you are behind a proxy, and whether you are aware of changes that have been made to your internet browser by your network or PC administrator, you need to configure Maven accordingly too, for Maven to work in a snap.

Check your proxy settings

Here is how you can verify your proxy settings, information which you would need for putting it into Maven’s settings.xml.

Go to Internet Explorer (Sorry i that am using IE 6 for this demonstration, this is really for the benefit of those who have survived the big bang haha ><) > Tools > Internet Options > Connections > LAN Settings.

Take note of the host (singproxy.as) and the port number (80), you will need this for later.

Change your Maven proxy settings

Go to your Maven home directory, locate the file settings.xml in the conf directory.

* By modifying this file directory, we are changing the settings globally for users of this local machine, which is probably 99% of time what you would like to do, however if not, you can make changes to this at a user level.

Open up settings.xml, locate and edit the proxy settings. Using the host and port number obtained from the above step, edit, save, and close the descriptor (settings.xml).

<proxies>
  <proxy>
    <id>my office proxy</id>
    <active>true</active>
    <protocol>http</protocol>
    <username>chinboon</username>
    <password>password</password>
    <host>singproxy.as</host>
    <port>80</port>
    <nonProxyHosts>*.gij|*.omnia|*.as|10.*|*.local|*.quest.com|*.toadsoft.com</nonProxyHosts>
  </proxy>
</proxies>

Verify changes made

In the last step, you could verify the changes have been made successfully by going back to do what was initially stopping you, these errors should go away. For my situation where because of the proxy settings, Maven was unable to down the index from the public repository, and this problem went away for me.

Maven is able to download and index my local m2 repository. :)

Still having problems?

If you are using Eclipse, then chances are that you are using the embedded Maven installation managed by your plugin exclusively, and it can become troublesome to maintain.

Check if you are using an embedded Maven installation, add the external installation that you have installed by yourself, i.e. the one at C:/maven/xxxx. Verify that the settings.xml is the one you have edited in the above steps.

:) Have lots of fun playing with Maven!
