Attribute duplication importing HoloEverywhere and ActionbarSherlock in Eclipse

Attribute duplication importing HoloEverywhere and ActionbarSherlock in
Eclipse

I have been struggling with this problem for hours now. I have tried all
tips I found at StackOverflow, but they did not help me.
The problem:
I have imported HoloEverywhere in Eclipse. I then imported
ActionbarSherlock into HoloEverywhere, as is said here only to get a bunch
of errors. Also, R.java is not being generated for the HoloEverywhere
project (I tried cleaning all projects, didn't work).
Judging by the log output, I'd say there are repeating attribute names in
the ActionbarSherlock and HoloEverywhere projects. How do I fix that?
Here is part of the log:
