====== Maven: Behind Proxy Server ======
  - Go to your maven local repository directory. e.g: c:\user\YOUR_LOGIN\.m2 for MS Windows.
  - Create a file name ''settings.xml''
  - In this file add:

<code>
<settings>
  <proxies>
   <proxy>
      <id>http</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>YOUR_PROXY_SERVER</host>
      <port>YOUR_PROXY_PORT</port>
      <username>YOUR_USER_NAME_IF_NEEDED</username>
      <password>YOUR_PASSWORD_IF_NEEDED</password>
    </proxy>
   <proxy>
      <id>https</id>
      <active>true</active>
      <protocol>https</protocol>
      <host>YOUR_PROXY_SERVER</host>
      <port>YOUR_PROXY_PORT</port>
      <username>YOUR_USER_NAME_IF_NEEDED</username>
