There seems to be no option in STS 3.6.1 to create a Roo app. While Googling I noticed this question for the same problem in version 3.5.0, and the sloution was to install Roo to STS manually as it is no longer included. Sweet, so I did that.
I installed it from the STS dashboard and after installation was complete and STS was re-started the dashboard shows this (so the installation was successful):
And lo and behold... still no option to creat a Spring Roo app!
So... how can I find the option to create a Spring Roo app from within Spring tool Suite?
You must install "Spring IDE - Roo Extension" too:
Then "Create Roo Project" will be ready:
Try to use Help -> Install new software And select SpringSorce Update Site to install Spring-Roo related features.
Anyway, you could run the Spring Roo shell on the systems shell to create the project (STS is great tool, but it isn't required to work with Roo).
Good luck!
