Múltiples archivos de bibliografía para cada capítulo con una bibliografía al final.

Múltiples archivos de bibliografía para cada capítulo con una bibliografía al final.

Estoy escribiendo el manuscrito de mi tesis usando el classicthesispaquete. Tengo cuatro archivos de bibliografía (archivos .bib), uno para cada capítulo, en una carpeta llamada "bibliografías". Cuando ejecuto el archivo principal, se compila correctamente pero las citas y la bibliografía no aparecen y no recibo ningún mensaje de error. Entonces, no estoy seguro de cuál es el problema. Obtengo claves de citas en negrita en lugar de citas en el texto y sin bibliografía. Utilizo PdfLaTeX + Bib(la)tex + PdfLaTeX (x2) + View Pdf para compilar usando TexMaker.

No necesito bibliografías separadas para cada capítulo sino una única bibliografía para toda la tesis.

Le agradecería su ayuda. A continuación se muestra la información sobre el código.

Tengo el siguiente código en el archivo principal:

\addbibresource{bibliographies/chap1.bib}
\addbibresource{bibliographies/chap2.bib}
\addbibresource{bibliographies/chap3.bib}
\addbibresource{bibliographies/chap4.bib}
.

\cleardoublepage\include{FrontBackmatter/Bibliography}

y en el bibliography.tex, tengo el siguiente código:

\defbibheading{bibintoc}[\bibname]{%
  \phantomsection
  \manualmark
  \markboth{\spacedlowsmallcaps{#1}}{\spacedlowsmallcaps{#1}}%
  \addtocontents{toc}{\protect\vspace{\beforebibskip}}%
  \addcontentsline{toc}{chapter}{\tocEntry{#1}}%
  \chapter*{#1}%
}
\printbibliography[heading=bibintoc]

y en el classicthesis-config.tex, tengo el siguiente código:
