Google's Scholar bibtex not working

Question

I'm not sure why I see no references shown ... I'm copy pasting from google scholar.

I've already done:

• pdflatex bibtex pdflatex pdflatex
• latex bibtex latex

Here's my code:

    \documentclass{article}
    \begin{document}
     \section{intro} % (fold)
     \label{sec:intro}
       \nocite{*}
     % section intro (end)
     \bibliography{refs}
    \end{document}

and the bib file

@book{sommerville2003engenharia,
  title={Engenharia de software},
  author={Sommerville, Ian and Melnikoff, Selma Shin Shimizu and Arakaki,Reginaldo and de Andrade Barbosa, Edilson},
  volume={6},
  year={2003},
  publisher={Addison Wesley S{\~a}o Paulo}
}
@book{pressman2016engenharia,
  title={Engenharia de Software-8{\textordfeminine} Edi{\c{c}}{\~a}o},
  author={Pressman, Roger and Maxim, Bruce},
  year={2016},
  publisher={McGraw Hill Brasil}
}

I've tried both BEAMER and ARTICLE classes, and nothing shown ... any help?

Answer 1

Take a look at the MWE that just worked for me. You need to add the requested style to the code.

\documentclass{article}
\begin{document}
 \section{intro} % (fold)
 \label{sec:intro}

  This is my work, I am citing \cite{pressman2016engenharia} and \cite{sommerville2003engenharia}

 % section intro (end)
 \bibliographystyle{unsrt}
 \bibliography{refs}
\end{document}

This compiles as,
