# Beamer + apacite: Citation undefined [duplicate]

I am doing a presentation with the beamer class using the metropolis theme. Currently I am using RStudio and compile the file with XeLaTeX. Texmaker is an alternative.

How to make biblatex behave like apacite? - did not work for me. May be I need to compile with more than just 1x XeLaTeX?

I would prefer to use Bibtex with apacite being able to just include a .bib file for \bibliography. However, I read that there exist some conflicts?

Errors:
- Rerun to get \PageLabels entry
- Citation ... undefined

\documentclass{beamer}
\usepackage{appendixnumberbeamer}

% various symbols
\usepackage{gensymb}

% bibliographystyle
\usepackage{apacite}

% Bilbliography
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@Misc{Ref1,
author = {{Test author}},
title  = {Test title},
year   = {2016},
url    = {http://testurl.com=},
}
\end{filecontents}

\usetheme[sectionpage = progressbar, numbering = fraction]{metropolis}

• Try with the second example from tex.stackexchange.com/questions/23651/…. It works fine with metropolis theme, if compiled with xelatex, biber, xelatex, xelatex – user36296 Sep 29 '16 at 13:27
• Thanks, it works. I now use Texmaker with a custom "quick build" command compiling xelatex, biber, xelatex, xelatex -> xelatex % | biber % | xelatex % | xelatex % referring to this answer: tex.stackexchange.com/a/154788/104937. RStudio seems to be to to basic for this approach atm. Add it as an answer and I´ll accept it! – pat-s Sep 29 '16 at 14:16
