LyX ⇒ Lyx error message: Repeated Entry

[christo_91]

Hi,

I've just updated the bibliography list for my Lyx document (same file location and file name), but when I click to preview the PDF the following error comes up (XXXX is the file extension):

Repeated entry---line 4310 of file 23C_XXXX_library.bib

If I click Show Output Anyway it works fine, but I'd rather get rid of the error message if I can.

Any ideas?

Thanks!

This happens if you have a bib-file (or more than one bib-files) with entries with the same key, e.g. with

Code: Select all

\begin{filecontents*}{\jobname.bib}
  @article{test,
    title={Test},
  }
  @article{test,
    title={Test repeated},
  }
}
\end{filecontents*}
\documentclass{article}
\bibliographystyle{unsrt}
\begin{document}
\nocite{*}
\bibliography{\jobname}
\end{document}

the bibtex run results in:

Code: Select all

This is BibTeX, Version 0.99d (TeX Live 2019)
The top-level auxiliary file: test.aux
The style file: unsrt.bst
Database file #1: test.bib
Repeated entry---line 4 of file test.bib
 :   @article{test
 :                ,
I'm skipping whatever remains of this entry
Warning--empty author in test
Warning--empty journal in test
Warning--empty year in test
(There was 1 error message)

Changing the key of the second entry from test to testB fixes the issue.

So you have to look into your bib-file and see where there is an identical key like the one of the entry in line 4310 and change one of the keys or remove the duplicate.
