间歇性 TFS 代理错误答案

【问题描述】：

我目前正在工作中设置 TFS 自动构建和部署，但遇到了间歇性错误。

我正在使用带有本地 TFS 代理的 Visual Studio Team Services (VSTS)。这在某些时候工作得非常好，然后代理在 VSTS 中随机出现空闲，即使代理作业仍在运行。

在代理的日志中出现以下错误：

有什么可能导致这种情况的想法吗？

【问题讨论】：

您使用哪个版本的 Agent.Version？你在代理后面运行代理吗？这个代理还在工作吗？

标签： tfs tfsbuild

【解决方案1】：

代理不工作时，状态会显示空闲。那除外。

在您对构建进行排队时检查您的代理是否正在工作。如果代理不起作用，请尝试下载最新版本 2.108.0 并重新部署。
