# Latex warning: Empty Bibliography on input [closed]

I have a problem with generating the bibliography at the end of the chapter. Translation doing the Windows command line in: xelatex main.tex. The files have UTF8 encoding. I use XeTeX, Version 3.1415926-2.4-0.9998 (MiKTeX 2.9 64-bit). In the log file are following warnings:

• Citation 'Pinker2006' on page 4 undefined on input line 6.
• Empty bibliography on input line 13.
• There were undefined references.
• Please (re)run Biber on the file.

I´m able to run: biber main.bcf. I get:

• info: This is Biber 1.1
• Warning: Found biblatex control file version 2.2, expected version 2.0
• Writing 'main.bbl' with encoding UTF-8

Now if I make a new translation, everything is fine. My question is why the translation does not generate a correct file main.bbl? By default, I use Texlipse with the following settings:

and

MWE:

1. main file: main.tex

\documentclass{article}
\usepackage{hyperref}
\usepackage[backend=biber]{biblatex}

\begin{document}
word\cite{Pinker2006}
\printbibliography
\end{document}


1. biblio file: library.bib

 % This file was created with JabRef 2.8.1.
% Encoding: UTF8

@BOOK{Pinker2006,
title = {Číslicové systémy a jazyk VHDL},
year = {2006},
author = {Pinker, Jiří; Poupa, Maritn},
isbn = {80-7300-198-5},
pagetotal = {352},
}


Latex says:

Package biblatex Warning: Please (re)run Biber on the file:
(biblatex)                main
(biblatex)                and rerun LaTeX afterwards.

Do you really think that this code is a "MWE", a minimal example? Beside this: the current biber version of miktex is 1.4., and biblatex has version 2.4. You should keep them in sync. And check your blg-file if your system is really calling biber and not bibtex. – Ulrike Fischer Jan 7 at 8:32
@jafan You've got various blank lines and similar which I think are confusing the Markdown. As Ulrike says, this is far from a minimal example, and reducing it will help us help you and the formatting system as well. – Joseph Wright Jan 7 at 8:36
I thought biber is part of the MiKTeX. I believe that when I doing regular update MiKTeX, that makes actual biber too. – jafan Jan 7 at 10:35
I don't have a 64bit-miktex, I don't know if it now contains biber and updates it (it hasn't some time ago tex.stackexchange.com/questions/63039/…). But if yes then you should update in admin + user mode to get really all new versions. – Ulrike Fischer Jan 7 at 11:28
@Ulrike Fischer I think that the biber is already part MikTeX 64 bit edition. I think my problem is that the biber generates an empty file main.bcf. If I run it manually, the file (main.bcf) is filled with the relevant data and everything is all right. – jafan Jan 7 at 11:56
