title: Flyway: unable to load custom config file in cmd line
body: <p>I created a new config file called "compare.conf" &amp; placed it in 'conf' folder.</p>
  
  <p>When I run the below command, I get the following error:</p>
  
  <p>PS C:\Projects\Learning\Test\flyway-3.2.1> <strong>.\flyway -configFile=conf\compare.conf info</strong></p>
  
  <p>Flyway 3.2.1 by Boxfuse</p>
  
  <p>ERROR: Unable to load config file: C:\Projects\Learning\Test\flyway-3.2.1\conf\compare</p>
  
  <p>If I run  the same command with absolute URL like below, it works fine. Is this a known issue in Flyway?</p>
  
  <p>PS C:\Projects\Learning\Test\flyway-3.2.1> .\flyway -configFile=<strong>C:\Projects\Learning\Test\flyway-3.2.1\conf\compare.conf</strong> info</p>
