我们的构建在TFS构建服务器上失败，并且有时会出现相同的错误。
我在其中一个项目上收到此消息（错误是指WebApi项目）：
导入的项目＆＃34; C：\ Program Files （86）\的MSBuild \ 12.0 \ BIN \ Microsoft.CompactFramework.CSharp.targets＆＃34;是 未找到。确认声明中的路径是 正确，并且该文件存在于磁盘上。
这个在另一个项目上（在智能设备项目上）：
导入的项目＆＃34; C：\ Program Files （86）\的MSBuild \微软\ VisualStudio的\ V12.0 \ web应用\ Microsoft.WebApplication.targets＆＃34; 没找到。确认声明中的路径是 正确，并且该文件存在于磁盘上。
通常这意味着该文件不在那里，应该是安装包含目标文件的工具还是从开发人员机器手动复制它们。我之前在那种情况下已经看过它并且很容易解决它，因为它是一个微不足道的问题。
问题是，文件在那里！构建似乎随机失败，这对我来说非常模糊。如果我们选择＆＃39;重试构建＆＃39;几次，构建正常进行。有时，构建只是第一次工作，然后它开始显示此错误。我没有发现任何关于何时发生的模式。
文件本身绝对没有什么特别之处。我认为他们在某种程度上缺少某些权限，但它们具有与其他附带文件相同的安全设置。
我不知道在这里调查什么。该消息指出文件丢失但文件在那里。它间歇性发生的事实更成问题。
这是在TFS 2013构建计算机上发生的。安装TFS后，安装了Visual Studio 2013 Ultimate。我们使用TFS2012在公司中建立了另一个构建VM，我从未见过如此奇怪的行为。

我忘了提及它，但是在包含web项目的构建中还有一堆随机警告。它们仅在出现关于.targets文件的错误时出现，并且不会显示在其他构建上。也许这与以下事实有关：一个是.Net4.5（网络），另一个是.Net3.5cf：

确定。在Dylan的评论之后，我去了构建日志，以确认＆＃34;只有一个代理运行构建，令我惊讶的是：
Successful Build: Run on agent (reserved build agent Build2014 - Agent1)
Failed Build: Run on agent (reserved build agent TFS2013 - Agent1)
Build2014是我们的构建VM，而TFS2013是我们的源代码控制器。
在TFS2013上安装TFS 2013时，会在同一台计算机上安装构建代理程序。安装在单独计算机上的控制器也具有同名的代理程序。这意味着控制器正在选择其中一个，每当它们到达TFS机器时，构建失败（因为那里没有故意的环境）。
在TFS机器上删除错误安装的代理是这里的方法。
答案 0 :(得分：3)
您确定您的构建始终在同一构建代理/服务器上运行吗？您是否可以设置多个构建代理并且它仅适用于某些构建代理？
