In this blog post we see how to update the Grails version of our application for a Grails 3 application. In previous Grails versions there was a special command to upgrade, but with Grails 3 it is much simpler. To update an application to a newer version in the Grails 3.0.x range we only have to change the value of the property grailsVersion in the file gradle.properties.
# gradle.properties grailsVersion=3.0.8 gradleWrapperVersion=2.3
After we have changed the value we run the clean and compile tasks so all dependencies are up-to-date.
Written with Grails 3.0.8.
