suddenly there is a missing of domain, controller and someother folders in my project in GGTS 2.2.1 my imported project looks like following folder
As I understand the problem is that you don't see some folders (eg domain, controllers, ...) in project explorer. This happend to me once too.
The problem was that the imported projected didn't have .classpath file and when you were importing the project grails made one for you.
The solution is to copy-paste the original .classpath file or if you don't have the original try to create it from another project.
