In MobileFirst v8.0 you no longer use Studio to create "projects" to create Hybrid apps, rather you use the Cordova CLI to create a Cordova app, and also use the Cordova CLI to add the MobileFirst SDK (plug-in) to the Cordova app.
The Studio plug-in for Eclipse in v8.0 is used to expose functionality provided by the MobileFirst CLI (register app, open console, and so on...), and so it will work only if you will also have the MobileFirst CLI installed, as well as the THyM plug-in for Eclipse, which makes Eclipse into a dev environment for Cordova apps.
