Adding/Updating Resource Environment Provider custom properties using wsadmin

Step 1 :
Creating following directory structure

  WSAdmin (project_root)
     config
            rep       
     scripts
            rep

Step 2 :
     Copy portalDeploy.xml to WSAdmin folder.
     Copy resourceEnvProviders.cfg file to WSAdmin\config\rep folder.
     Copy resourceEnvProviders.py file to WSAdmin\scripts\rep folder.

Step 3 :
    Run following command - 
    <wp_profile>/bin>ws_ant.bat -f <WSAdmin folder path>\portalDeploy.xml crateUpdateREP

• portalDeploy.xml

<?xml version="1.0" encoding="UTF-8"?>
<project name="portaldeploy" basedir=".">
