Question

Ich habe das Problem, dass meine Arbeit quasi aus dem Nichts nicht mehr kompiliert wird, insbesondere das Literaturverzeichnis (ohne läuft es flüssig durch). Ich verwende classicthesisein Template, das ist ein richtiges Monster. Das Problem besteht allerdings auch weiterhin, wenn ich ein Minimalbeispiel mit der Standardklasse erstelle article.

\documentclass[]{article}

Ich kann das Problem nicht herausfinden und versuche es seit gestern. Die Fehlermeldung ist etwas mehrdeutig:

Zeile 23: File ended while scanning use of \field. \begin{document}
Zeile 27: Undefined control sequence. \begin{abstract}
Zeile 30: Missing number, treated as zero. \cite{Cleland2013}

Die vollständige Fehlermeldung, die man in der .logDatei erhält, wenn man versucht, den Eintrag aus der Frage zu zitieren, ist ein klein wenig hilfreicher als die Zusammenfassung Ihres Redakteurs

Die Zeile über der Fehlermeldung gibt Ihnen einen Hinweis, wo genau Sie nach dem Übeltäter suchen müssen. Der zitierte Text "Früheres, aktuelles und prognostiziertes zukünftiges Bevölkerungswachstum wird dargelegt." ist der Anfang des abstractFeldes in Ihrem Eintrag.

Wenn LaTeX %beim Lesen des Feldinhalts abstractaus der .bblDatei auf dieses Zeichen stößt, erhalten wir eine Fehlermeldung, da das %Zeichen den Rest der Zeile in einen Kommentar umwandelt, was bedeutet, dass die schließende geschweifte Klammer }am Ende des Felds nicht sichtbar ist.

Das führt dazu, dass

! File ended while scanning use of \field.

Fehler.

%Die Lösung besteht darin, das Zeichen im abstrakten Feld durch zu ersetzen \%.

Da die meisten Bibliographiestile das abstractFeld ohnehin ignorieren, wäre es vielleicht eine bessere Idee, das Feld einfach .bibvollständig aus der Datei zu entfernen.. (Dies kann von Biber im Handumdrehen erledigt werden, sieheFehler mit Prozentzeichen im Bib-Eingabefeld bei Verwendung von Biblatex/Biber, aber es istvielbesser, das Feld vollständig und direkt aus der Datei zu löschen .bib.) Wenn Sie die Zusammenfassung benötigen, ist es theoretisch möglich, das %s im laufenden Betrieb zu maskierenVerhindern, dass Biber in der Zusammenfassung an „%“-Zeichen erstickt?.
