title: How to connect Grails 3.0 to my local Mysql database
body: <p>I'm quite new with Grails and trying to connect my application to my local mysql database. Since I'm working with the latest version of Grails, I couldn't really find a lot of documentation to help me out. Is there any clear documentation which could guide me in the right direction?</p>
  
  <p>(I've tried the official documentation, but it seems to be out of date)</p>
