How to enable proxy setting in Maven

To enable proxy access in Maven, define the proxy server detail in {MAVEN_HOME}/conf/settings.xml

Note
There is a high chance your company is set up an HTTP proxy server to stop user connecting to the Internet directly. If you are behind a proxy, Maven will fail to download the project dependencies.

P.S Tested with Maven 3.6

1. Proxy Access

1. Open the Maven settings.xml, find proxies tag :

{MAVEN_HOME}/conf/settings.xml

<!-- proxies
   | This is a list of proxies which can be used on this machine to connect to the network.
   | Unless otherwise specified (by system property or command-line switch), the first proxy
   | specification in this list marked as active will be used.
   |-->
  <proxies>
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |
    <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>proxyuser</username>
      <password>proxypass</password>
      <host>proxy.host.net</host>
      <port>80</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
    -->
  </proxies>

1.2 Defined the proxy server setting like below :

<proxies>
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |
    <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>proxyuser</username>
      <password>proxypass</password>
      <host>proxy.host.net</host>
      <port>80</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
    -->
	
	<proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>favtuts</username>
      <password>password</password>
      <host>proxy.tuts.heomi.net</host>
      <port>8888</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
	
  </proxies>

1.3 Done, the Apache Maven should be able to connect to the Internet via the proxy server.
