编辑：
根据 moewe 的建议，MWE 现在确实很小了（我认为）。我.bib通过删除缩写来消除对多个文件的需要，并使主.bib文件更小（正如下面所示）。
这是日志（file.blg）：

看起来文件被提取了两次（因此出现重复键的警告）。但我不知道这与问题有何关系。
当使用biblatex（和biber）功能从远程位置获取.bib文件时，交叉引用无法解析。
考虑以下书目文件（bibliography.bib)：
@Article{a:watson:2014:01,
title = {The Evolution of Phenotypic Correlations and ``Developmental Memory''},
author = {Watson, Richard A. and Wagner, G{\"u}nter P. and Pavlicev, Mihaela and Weinreich, Daniel M. and Mills, Rob},
journal = {Evolution},
year = {2014},
month = apr,
volume = {68},
number = {4},
pages = {1124--1138},
doi = {10.1111/evo.12337},
url = {http://dx.doi.org/10.1111/evo.12337},
}
@InCollection{ic:bedau:2009:01,
title = {The Evolution of Complexity},
author = {Bedau, Mark A.},
pages = {111--130},
doi = {10.1007/978-1-4020-9636-5_8},
url = {http://dx.doi.org/10.1007/978-1-4020-9636-5_8},
crossref = {c:barberousse:2009:01},
}
@Collection{c:barberousse:2009:01,
editor = {Barberousse, Anouk and Morange, Michel and Pradeu, Thomas},
title = {Mapping the Future of Biology},
booktitle = {Mapping the Future of Biology},
subtitle = {Evolving Concepts and Theories},
publisher = {Springer Netherlands},
year = {2009},
doi = {10.1007/978-1-4020-9636-5},
url = {http://dx.doi.org/10.1007/978-1-4020-9636-5},
series = {Boston Studies in the Philosophy of Science},
volume = {266},
}
如果我ic:bedau:2009:01在使用 时引用\addbibresource{bibliography.bib}，则对 的交叉引用c:barberousse:2009:01将成功解析。\addbibresource[location=remote]{<url>.bib}但是，如果我在使用 时引用它，则交叉引用不会解析，除非我碰巧也在c:barberousse:2009:01文本中的其他地方引用。
我正在使用 的最新版本MacTeX并用 进行编译pdflatex -> biber -> pdflatex。
有什么想法吗？有人至少可以确认他们遇到了同样的问题吗？MWE 如下。
梅威瑟：
\documentclass{article}
\usepackage[backend=biber]{biblatex}
% If I fetch the file from a remote location, cross-refs are not resolved.
\addbibresource[location=remote]{https://dl.dropboxusercontent.com/u/47261882/bibliography.bib}
% If the file is stored locally, everything works okay.
% \addbibresource{bibliography.bib}
\begin{document}
% Does not resolve cross-reference.
\cite{a:watson:2014:01,ic:bedau:2009:01}.
% Resolves cross-reference because it is also cited explicitly.
% \cite{a:watson:2014:01,ic:bedau:2009:01,c:barberousse:2009:01}.
\printbibliography
\end{document}

这是一个错误，应该在 SourceForge 上的 DEV 文件夹中提供的 biber 1.9 中得到纠正。您需要使用 biblatex 2.9 DEV 版本和 biber 1.9（也在 SourceForge 上）。它不必要地多次获取远程源。
