How to use a single .war for several grails environments in AWS Elastic Beanstalk?
===

I run several environments of my Grails application up in Elastic Beanstalk.  It would be a big timesaver  to not have to build and upload different .war files just for the different environments (I have all the environmental differences passed in as configuration).  As per this article http://mrhaki.blogspot.ca/2011/02/grails-goodness-one-war-to-rule-them.html, it is possible to use a single .war and set the environment dynamically by passing the grails.env property, but it doesn't seem possible to do so as beanstalk limits you to a predefined set of named system properties (JDBC_CONNECTION_STRING, PARAM1, PARAM2, etc)

What would be my best approach here?
