在TFS 2018中的获取源步骤期间，由于超时而导致构建失败

Question

我们的TFS构建代理在Get Sources步骤中看似随机出现问题，git fetch命令挂起并在一小时后超时。

日志的最后一部分显示它已获得所需的一切但决定停止直到它超时。

我们有4个构建代理程序设置，通常一两个在构建期间每晚都有这个问题。

当我查看代理程序目录并运行git status命令时，我收到一条消息：

Rename from 'C:\BuildAgent1\_work\1\s\.git\index.lock' to C:\BuildAgent1\_work\1\s\.git\index' failed. Should I try again? (y/n)

输入＆＃39; y＆＃39;只是导致该消息重复。查看.git /文件夹，不存在index.lock文件。

手动发布另一个构建版本，构建过程中没有问题。

为什么在获取所有内容后，构建会挂起？

Answer 1

因此，此问题的解决方案是清理sources目录。

• 将清洁设置为true，清洁选项选择获取来源步骤下的Sources directory。
• 或者，您可以在代理上手动删除源文件夹 机。 （例如：C:\Agent\_work\2\s\，基本上删除了.git 文件夹将解决问题C:\Agent\_work\2\s\.git）
