Unable to convert classes into dex format. See the Console for details

Hello Folks,

I am here to discuss some unusual error which I got while building for my gear VR in unity 5.1.2f1.

The screenshot is attached. Please help me and let me know what is the possible way to fix it.

The console error message:

I ran into exactly same issue with same Unity & Moible SDK version.
Looked lots of info, still not fixed yet, except removing those plugin lib/jar, which is not the right way IMO.
