title: In the Eclipse, how to set environment variables for the whole project (Ubuntu)
body: <p>Thanks for viewing my question first! I am developing a PHP project with AWS in the Eclipse.</p>
  
  <p>As the AWS SDK needs the environment variables of AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY, I am struggling with how to set them in Eclipse. Currently, it works perfectly in Terminal and single file in Eclipse. As I can set the two environment variables for single file:<a href="https://i.stack.imgur.com/CRSqL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CRSqL.png" alt="enter image description here"></a></p>
  
  <p>I aslo tried to set them in etc/environment, but I do not know it does not work.</p>
  
  <p>Could you tell me how to set the environment for the whole PHP project?</p>
  
  <p>System: Ubuntu 14.04
  Eclipse version: 
  "Eclipse for PHP Developers
  Version: Mars.2 Release (4.5.2)
  Build id: 20160218-0600"</p>
