When running this sample code:

usepackage[british]babel

usepackagenatbib

Hello World citegreenwood_theoretical_2016

enddocument

bibliographyBibliography
bibliographystyleplain

I keep getting the warning:

'Citation greenwood_theoretical_2016 on page 1 undefined on input line 10'

and the references are marked as '?' in the document.

I am using Sublime Text 3.2 with LaTeXTools on macOS High Sierra.

The builder is set to 'basic' so it runs:

pdflatex
bibtex
pdflatex
pdflatex

I exported my bibliography from Zotero (Format: Bibtex; Encoding: UTF-8) and checked the 'Bibliography.bib' file (which is in the same directory) and the citations seem to be correct (example):

@articlegreenwood_theoretical_2016,
title = Theoretical, contemporary observational and palaeo-perspectives on ice sheet hydrology: Processes and products,
volume = 155,
issn = 0012-8252,

Using biblatex instead of natbib gives me the reference's label in square brackets i.e.

Hello World [greenwood_theoretical_2016]

I also tried using different styles but nothing has changed.

I know there have been lots of questions about this, but nothing seems to work here.

In your given code are some issues:

1. The order of calling bibliographystyle and bibliography should be changed in your code (style first!).


2. With loading natbib you should better use style plainnat instead plain
   


3. You have enddocument before you calls the bibliography. That means the code after enddocument is not executed.

Please use the following code:

RequirePackagefilecontents
beginfilecontents*Bibliography.bib

and see the expected result:

If you want to get the bibliography numbered add option numbers to natbib:

usepackage[numbers]natbib

The correct code to compile with biblatex is

documentclass[11pt,a4paper]scrartcl

usepackage[T1]fontenc
usepackage[utf8]inputenc
usepackage[british]babel
usepackage[onehalfspacing]setspace

usepackagecsquotes

 backend=biber, % <=====================================
]biblatex
addbibresourceBibliography.bib % Bibliography <=======


begindocument

Hello World citegreenwood_theoretical_2016

printbibliography

enddocument

with the result:

Not tested but I am almost sure that the command bibliographystyleplain should be before the command bibliographyBibliography and most important (that here I am sure), that both commands should be before of the enddocument command.

Please try it and answer if it is ok.
