title: grails how load external config file before config.groovy
body: <p>Grails app where based on my external properties file, I then want to load appropriate provider in the config.groovy (grails.plugins.springsecurity.providerNames). This means doing a check in config.groovy based on a property in the external config. Is there a way to load the external config before the config.groovy or other suggestions?   </p>
