在本地 vNext 构建代理上从 Visual Studio Team Services 触发构建在从存储库获取源时失败，可能是因为公司代理。VSTS 上的构建日志显示：

2016-01-28T12:35:03.7688078Z Syncing repository: MyProject (TFVC)

2016-01-28T12:35:05.3257849Z ##[error]Prepare repository failed with exception.

在构建服务器上，代理日志显示以下异常：

关于 407 代理身份验证错误有很多类似的问题，建议更改配置文件，但没有具体针对 vNext 构建代理的问题。是否有某个配置文件可以编辑以解决此问题？

您需要更改的配置文件是VsoWorker.exe.config，可以在以下位置找到C:\BuildAgent\TFS_Build\agent\agent\Worker。

在<configuration>块中添加以下代码：

<system.net>
  <defaultProxy useDefaultCredentials="true">
  </defaultProxy>
</system.net>

我在公司代理后面使用 VSTS，但已经在全球范围内设置了我的 git 代理。如果我已经这样做了（因此可以从命令行从集合中提取），那么使用最新的 vso 代理它就可以工作：
