BibLaTex empty bibliography [duplicate]

Question

I'm working with TeXShop 3.61 and I'm currently switching from natbib to biblatex. Despite having tried for hours and read through all other entries, I still can't make it work.

.tex Document:

\documentclass{article}
\usepackage[backend=biber]{biblatex}
\bibliography{Ohne-Titel}
\begin{document}
Test test test \cite{Lee2009a}
\printbibliography
\end{document}

.aux File:

\relax 
\abx@aux@sortscheme{nty}
\abx@aux@cite{Lee2009a}
\@writefile{toc}{\boolfalse {citerequest}\boolfalse {citetracker}\boolfalse {pagetracker}\boolfalse {backtracker}\relax }
\@writefile{lof}{\boolfalse {citerequest}\boolfalse {citetracker}\boolfalse {pagetracker}\boolfalse {backtracker}\relax }
\@writefile{lot}{\boolfalse {citerequest}\boolfalse {citetracker}\boolfalse {pagetracker}\boolfalse {backtracker}\relax }

.bib Entry:

@article{Lee2009a,
author = {Lee, Geun},
file = {:Users/JulianLeitner/Library/Application Support/Mendeley Desktop/Downloaded/Lee - 2009 - A Theory of Soft Power and Korea's Soft Power Strategy.pdf:pdf},
journal = {The Korean Journal of Defense Analysis},
number = {2},
pages = {205--218},
title = {{A Theory of Soft Power and Korea's Soft Power Strategy}},
volume = {21},
year = {2009}
}

And here the error message:

 LaTeX Warning: Citation 'Lee2009a' on page 1 undefined on input line 5.

 LaTeX Warning: Empty bibliography on input line 6.

 [1{/usr/local/texlive/2015/texmf-var/fonts/map/pdftex/updmap/pdftex.map}]
 (./Ohne-Titel.aux)

 LaTeX Warning: There were undefined references.

To compile I simply use the Macro --> applescript --> bibliography.

Any help would be highly appreciated! Julian

Answer 1

Since biblatex is used, the bib-file should be specified with addbibresource{...}.

\bibliography is 'deprecated` and shouldn't be used any longer.

And use biber after pdflatex, compile twice (or better three times!)

\documentclass{article}
\usepackage[backend=biber]{biblatex}
\addbibresource{Ohne-Titel.bib}
\begin{document}
Test test test \cite{Lee2009a}
\printbibliography
\end{document}

Ohne-Titel.bib

@article{Lee2009a,
author = {Lee, Geun},
file = {:Users/JulianLeitner/Library/Application Support/Mendeley Desktop/Downloaded/Lee - 2009 - A Theory of Soft Power and Korea's Soft Power Strategy.pdf:pdf},
journal = {The Korean Journal of Defense Analysis},
number = {2},
pages = {205--218},
title = {{A Theory of Soft Power and Korea's Soft Power Strategy}},
volume = {21},
year = {2009}
}
