Question

在内部部署vNext构建代理上从Visual Studio Team Services触发构建在从repo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)
2016-01-28T12:35:03.7688078Z workspaceName=ws_3_3

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：

16:17:14.895983 System.AggregateException: One or more errors occurred. ---> Microsoft.TeamFoundation.DistributedTask.Agent.Common.AgentExecutionTerminationException: Prepare repository failed with exception. ---> Microsoft.TeamFoundation.TeamFoundationServiceUnavailableException: HTTP code 407: Proxy Authentication Required ---> System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required.

关于407代理身份验证错误有很多类似的问题，有关配置文件要更改的建议，但没有特定于vNext构建代理的问题。是否有我可以编辑的配置文件来修复此问题？

Answer 1

您需要更改的配置文件为VsoWorker.exe.config，可在以下位置C:\BuildAgent\TFS_Build\agent\agent\Worker中找到。

在<configuration>块中添加以下代码：

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

Answer 2

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（也可以从命令行中收集），那么使用最新的vso代理就可以了：

TFS vNext构建代理失败，出现407代理身份验证错误
