I am referring to https://www.overleaf.com/learn/latex/How_to_Write_a_Thesis_in_LaTeX_(Part_4):_Bibliographies_with_BibLaTeX for creation of a Thesis Document in LaTex through TexShop. My LaTex document has several chapters like Introduction, Methodology, etc. I have created a references file references.bib in the same directory as the main file main.tex. Now, I have citations present in the references.bib file and I have cited each citation in the corresponding chapters at places they appear, eg. in Introduction cited paper1 as cite{paper1}, in Introduction cited paper2 as cite{paper2}, cite paper3 in Methodology as cite{paper3} etc. The references in the references.bib file are in the following format:-

@article{paper1,

    author        = {Albert Einstein},

    title         = {Zur Elektrodynamik bewegter K{"o}rper. (German) [On the electrodynamics of moving bodies]},

    journaltitle  = {Annalen der Physik},

    year          = {1905},

    volume        = {322},

    number        = {10},

    pages         = {891-921},

    doi           = {http://dx.doi.org/10.1002/andp.19053221004}

}



@online{paper2,

    author        = {Donald Knuth},

    title         = {Knuth: Computers and Typesetting},

    year          = {1984},

    url           = {http://www-cs-faculty.stanford.edu/~uno/abcde.html}

}



@book{paper3,

    author        = {Michel Goossens and Frank Mittelbach and Alexander Samarin},

    title         = {The LaTeX Companion},

    year          = {1993},

    publisher     = {Addison-Wesley},

    location      = {Reading, Massachusetts}

}

I am now stuck in the situation that how I can compile the references and generate the main.tex LaTex file so that I have one final list of bibliography for the entire document (means references 1-3) after the conclusion section of the thesis. I am using the following for this purpose at the beginning of document:-

usepackage{biblatex}

addbibresource{references.bib}

And this for displaying references at the place I need them to be i.e. after the Conclusion Section.

printbibliography

I am able to compile the LaTex main.tex file easily and the whole document generates without the references, but when I try to do BibTex on the main.tex file, I get the following errors:-

This is BibTeX, Version 0.99d (TeX Live 2018)

The top-level auxiliary file: main.aux

I found no citation commands---while reading file main.aux

I found no bibdata command---while reading file main.aux

I found no bibstyle command---while reading file main.aux

(There were 3 error messages)

I am new to using LaTex, referred to other documentation as well but still am confused including the website I mentioned which I am primarily referring to. I would really appreciate if you could kindly help me with this. Cheers and Thanks a lot!
