With NetBeans 8.2 isn´t necessary the old plugin for JET.Now in the IDE you can create a sample app.
We have the next options from “New projects”
Anyway, I think is a better option use a yeoman to cretae a basic app based on a template.
we have differents templates blank,basic, navbar or navdrawer
To create a aplication you can do
yo oraclejet MyAppNavDrawer –template=navdrawer
Another option is create a hybrid application with this kind of sentence
yo oraclejet:hybrid app –appname=SampleNavBar –template=navbar –platform=android
In this section you can find information about prerequisits: Node,yeoman,grunt,cordova(hybrid)
If we had already been working on previous versions with jet and node I recommend you that you update node and the necessary complements as yeoman.
In my case I gave this error before doing it.
