Oracle JET and Netbeans.

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.
