团队城市（Teamcity）NuGet仓库损坏。

Question

我的谷歌搜索能力不足...我找不到其他的错误实例。

自从一天前开始，我的teamcity nuget仓库就一直出问题。从仓库下载NuGet时会失败并出现意外的EOF或损坏的软件包警告。

据我所知，这与硬件故障无关，虚拟机和虚拟机主机没有报告磁盘错误。

更令人沮丧的是，teamcity日志文件“teamcity-javaLogging-2013-07-17.log”不受限制地增长（在我输入这些文字的时间内增加了3GB，而正常情况下每天为10MB），其中包含以下类似的堆栈跟踪信息。

我的Teamcity版本为7.1.5（版本号24400）

有人知道如何从这种故障中恢复吗？

我还没有勇气清除我能在teamcity管理页面上找到的所有缓存（Administration > Diagnostics > Caches），因为该页面上有一个令人惊恐的黄色警告，不要这样做。

以下是我得到的堆栈跟踪信息样本。

Answer 1

据我所知，TeamCity NuGet服务受到“管理 | 项目相关设置 | 构建历史记录清理”中定义的工件清理策略的限制，因此请确保您的软件包仍然存在！

我的个人建议始终是设置一个专用的nuget服务器。您可以克隆GitHub上的官方NugetGallery项目来免费设置一个：那是nuget.org使用的相同代码库，因此您将拥有熟悉的UI和更高的性能（NugetGallery利用了Lucene.NET索引功能）。

Answer 2

如Remco所说，您可以通过访问http://{teamcity}/admin/admin.html?item=diagnostics&tab=cache并在“buildsMetadata”旁边点击“重置”来清除软件包缓存。这将从您的源中删除所有NuGet软件包，直到重新索引。

您可以通过调用TeamCity的REST API来重新索引单个构建生成的NuGet软件包。要重新索引所有构建，您需要编写一个脚本循环遍历所有构建并重新索引每个构建。

Answer 3

似乎 TeamCity NuGet 服务器的索引出现了某种故障，但软件包没有问题，因此清除缓存是解决方案。

然而，我还没有找到如何重新填充索引的方法。

请注意，清除 nuget 包缓存会从 TeamCity NuGet 服务器中删除所有软件包，所以您需要从头开始...
