With the release of Android Studio 1.0 Google has declared AS to be the official IDE for Android (see the announcement here), signalling the beginning of the end for Eclipse/ADT support.
I have Java projects in Eclipse that use both ADT and GPE: corresponding client and server projects which share code. So I will eventually need to switch to AS, and will want to switch both my ADT and GPE projects at the same time, but I could go quickly (to get the benefits of AS when developing for Android), or only move when I have to because I like Eclipse and am unsure of the degree to which AS/IntelliJ replace GPE.
So, my question is, what is the status of GPE for Eclipse, and to what degree is GPE functionality supported in AS? Is Google cloud team still actively developing GPE (beyond necessary stuff like support for Luna)?
