Bibliography not showing up

[me7pako]

As the title suggests, the bibliography simply does not show up. I have tried running the main file with biber and following it with pdflatex multiple times but to no avail. The main file is nothing out of the ordinary so I did not include it here.

Any ideas what the issue can be?

Ok I found a workaround for anyone having the same issue as mine:
instead of those two lines in the preamble:

\usepackage[style=authoryear,backend=bibtex]{biblatex} %backend tells biblatex what you will be using to process the bibliography file
\addbibresource{main.bib}

I deleted them and put:

\usepackage{filecontents}
\begin{filecontents}{ [I put here mybiblography]}
\end{filecontents}

and inside the dcoument I removed:

\printbibliography[title=Bibliography]

And replaced it with

\nocite{*}
\bibliographystyle{ieeetr} %to print the bibliography with original typing order
\bibliography{jobname}

After that I would run the main.tex with bibtex and not with biber, and then pdflatex+makeindex+bibtex
