unity 5.2 plugin integration issue

I am having a world of trouble understanding how to integrate android plugins in unity under 5.2

The issue stems from the whole you can't have res folders in the root of Plugins/Android folder. So after some research i moved all my plugins to a libs folder, moved the res folder, and added the manifest file and properties file to create an android library. put the jar files in libs folder.

But a problem remains. It is unable to convert to dex. I get an error stating the following:

 stderr[

This I know happens when you have a duplicate library but I don't. I checked, and re installed everything! So at this moment i'm lost. How do I get this plugins to behave?
