Grails Goodness: Simple Script to Create WAR Files for Each Environment

We can create a new WAR file with the following Grails command:

$ grails test war dist/test.war

This will make a new WAR file in the dist directory with the name test.war. We use the test environments for the settings.

With the following Groovy script we create a WAR file in the dist for each environment. We use application.properties to get the application name and version and use it to create the WAR filename.
