Test your applications against the nightly builds of Grails

One of the cool things the team at Sky used to do was to test the codebase against the latest nightly build of Grails.

This allowed us to quickly catch regressions or incompatibilities as soon as they were checked into Grails. 

Here is a bash script that you can add to Jenkins to do so for Grails 2.3.x 

#download grails nightly
curl -O http://hudson.grails.org/job/grails_core_2.3.x/lastSuccessfulBuild/artifact/build/distributions/${GRAILS_NIGHTLY}.zip

#install jar files into local maven repository
for f in *BUILD-SNAPSHOT.pom; 
   mvn install:install-file -Dfile=${f/.pom/.jar} -DpomFile=$f 
cd ../../

#set environment variables
export PATH="$PATH:$GRAILS_HOME/bin"

#test grails app
grails upgrade --non-interactive
grails test-app --non-interactive

Set it to run once and day and you can guarantee that your code is compatible with changes that are happening within Grails.

Caution: Your project needs to be compatible with at least Grails 2.3.0 for this script to work as the versioning for the Tomcat and Hibernate plugins have changed from previous versions.
