Biber 生成空的 bbl 文件

Question

我一直想从 BibTeX 切换到 BibLaTeX，所以今天我想试一试。在阅读手册后，我最终设法将所有命令转换为新语法。pdfLaTeX 和 Biber 都没有给出任何错误，但是 bbl 文件是空的，我收到有关未定义引用和空参考书目的警告。我在这个论坛上读到过许多类似的问题，但没有一个能解决我的问题。由于 BibLaTeX 文档是少数几个我没有完整阅读过的软件包文档之一，我认为我天真地做错了什么。我的 tex 文件：

\documentclass[fontsize = 11pt,paper = a4,ngerman]{scrbook}

\usepackage[ngerman,british]{babel}
\usepackage[utf8]{inputenc}
\usepackage[backend=biber,bibstyle=authoryear]{biblatex}
\usepackage{csquotes}
\addbibresource{test.bib}

\begin{document}
Test \cite{OLED}.
\end{document}

测试.bib：

@Book{OLED,
    author = {Hari Singh Nalwa and Lauren Shea Rohwer},
    title = {Organic Light-Emitting Diodes},
    series = {Handbook of Luminescence, Display Materials and Devices},
    year = {2003},
    publisher = {American Scientific Publishers}
}

即使安装了 BibLaTeX 3.0，Biber 仍会在 blg 文件中给出版本警告：
