Upgrading Grails: from 1.1.x to 1.2.0

The new Grails Version 1.2 was release right before Christmas 2009.

Compared to the time-consuming and nerve-wracking Grails Upgrade from 1.0 to 1.1 that users experienced, the upgrade to Version 1.2 is a lot easier.

This time the major showstopper is a bug in Grails’ build-in datepicker (see GRAILS-5593 and GRAILS-5610). This issue is already fixed in 1.2.1 trunk. So if you use the datepicker in your app, you should probably wait with the upgrade until 1.2.1 is released – which is scheduled to be released end of january 2010.

Some other issues that users could experience when upgrading to Grails 1.2 are listed in Robert Fletcher’s Blog:

The main imprevements in Grails 1.2 are:

  • Spring 3 integration
  • Dependency resolution DSL
  • Per-method transactions in services
  • GORM improvements (e.g. Named Query Support)
  • Performance optimizations (GSP rendering improvements, GSPs are now precompiled)
