Simplify things by using the following settings.xml:
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
http://maven.apache.org/xsd/settings-1.0.0.xsd">
<proxies>
<proxy>
<id>myproxy</id>
<active>true</active>
<protocol>http</protocol>
<username>user</username> <!-- Put your username here -->
<password>pass</password> <!-- Put your password here -->
<host>123.45.6.78</host> <!-- Put the IP address of your proxy server here -->
<port>80</port> <!-- Put your proxy server's port number here -->
<nonProxyHosts>local.net|some.host.com</nonProxyHosts> <!-- Do not use this setting unless you know what you're doing. -->
</proxy>
</proxies>
</settings>
Under Linux/Unix, place it under ~/.m2/settings.xml. Under Windows place it under c:\documents and settings\youruser\.m2\settings.xml or c:\users\youruser\.m2\settings.xml.
You don’t need the <mirrors/>, <profiles/> and <settings/> sections, unless you really know what they’re for.
