我开始在 Overfleaf 上编写我的 LaTex 文档，现在我想继续使用 TexMaker 在本地编写它。
但是，当我构建文档（使用 Quickbuild 和 PdfLatex + biblatex + pdflatex (x2) + view pdf）时出现此错误：

Cloud Computing made the idea of on-demand, scalable and high available resources a low-cost reality. In the smartphone era, where devices (with limited computation and battery power) produce a massive quantity of data, Mobile Cloud Computing has become an hot topic in research community. In particular, it has been successfully exploited in the developement of many Augmented Reality (AR) applications designed for mobile devices, where local computation is too much expensive for the single smartphone. In this context, reduce the time needed for tasks computation gain advantages for both providers and end-users, giving a better user experience and saving battery life. In this paper we introduce CloudCache, a framework designed to improve performance of mobile AR applications, where previous (expensive) computations performed by the Back End system are reused in order to speedup similar tasks in the future, resulting the first memoization-like system . The design and implementation of CloudCache is described, where different tools from previous works in Computer Vision has been used to achieve the desired performance. Some of these tools has been parallelized to exploit the multi-cores architectures commonly presented in most of Cloud providers nowadays. CloudCache has been tested on three recognition Augmented Reality applications, where two new image datasets are presented to evaluate the system and the performance of the original applications has been greatly improved . \ldots

答案1
看起来所有 BibTeX 错误都是由于重复的键造成的，即.bib文件中有多个包含键的条目yianilos1993dataetc。BibTeX 不喜欢这种情况。如果您修剪.bib文件以删除重复的条目，那就应该可以了。
（Overleaf 目前将 BibTeX 错误视为警告，因此您仍然会看到编译完成并获得 PDF。）
