I was reading chapter 6.3.1. Specificly:
To remove Roo from a project, you need to import the project into Eclipse or SpringSource Tool Suite. Once the project has been imported into Eclipse, right-click the project name in Package Explorer and select Refactor > Push-In Refactor. If this option is missing, ensure that you have a recent version of AJDT installed.
I do not see the Push-in Refactor menu selection.
How do I " ensure that you have a recent version of AJDT installed" ?
