在CI环境中MSBuild"无法复制文件"

Question

我正在使用Hudson作为持续集成服务器.这些工作最终将启动MSBuild.每个人偶尔,我的构建失败,出现MSBuild的非代码编译错误:

C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets(2703,9): error MSB3021: Unable to copy file "..\Lib\Microsoft\Microsoft.Practices.Unity.Configuration.dll" to "bin\Debug\Microsoft.Practices.Unity.Configuration.dll". Access to the path 'bin\Debug\Microsoft.Practices.Unity.Configuration.dll' is denied.

当我检查'bin\Debug\Microsoft.Practices.Unity.Configuration.dll'时,我发现它是一个0字节的文件.

我不知道为什么这个文件有问题.有任何想法吗？

Answer 1

MS Build Copy任务具有无证功能,至少谷歌保持沉默.如果设置系统范围的环境变量MSBUILDALWAYSRETRY = 1此任务将重试复制文件,即使它在复制操作期间获得Access Denied异常

输出示例
