Upgrade Grails 2.5.0 to 2.5.1

I successfully upgrade Grails to the version 2.5.1It's quite simple.You only have to follow the release note about plugins update.
I met only one problem.I had this warning : Script 'Upgrade' not found.

To solve that issue, you have to select 3 (SetGrailsVersion) ant it will make the update.

|Running pre-compiled script
|Script 'Upgrade' not found, did you mean:
   1) MigrateDocs
   2) IntegrateWith
   3) SetGrailsVersion
   4) InstallDependency
   5) DependencyReport
Please make a selection or enter Q to quit: 3

With this update, I solved the following error : http://stackoverflow.com/questions/32562678/grails-plugin-error-class-path-resource-cannot-be-resolved
