When trying to build a gearvr project with the Online Subsystem Oculus plugin enabled you get a build error pretty quickly:

Any ideas what the problem is?
Building in development mode for ETC2 - project builds fine without this plugin. Should be supported for the gearvr at least according to Oculus
EDIT: also occurs in Preview 2
