替换字符串不工作从CMD

Question

调用的时候，我有以下PowerShell的命令从PowerShell中直接调用时工作完全正常：

Get-ChildItem -r -include 'AssemblyInfo.cs' ` 
| foreach-object { $a = $_.fullname; (get-content $a) ` 
| foreach-object { $_ -replace '((\[assembly:\sAssemblyVersion\(")(\d\.\d\.\d\.\d)("\)\]))', '$1[assembly:AssemblyInformationalVersion("$3-alpha")]' } ` 
| Out-File $_.fullname } 

然而，从CMD叫（我们Buildservers进程在cmd中运行）时它不会引发错误，但它也简化版，替换字符串如预期（它可以从任何CMD窗口转载）：

PowerShell -Command "(Get-ChildItem -r -include 'AssemblyInfo.cs') | foreach-object { $a = $_.fullname; (get-content $a) | foreach-object { $_ -replace '((\[assembly:\sAssemblyVersion\(")(\d\.\d\.\d\.\d)("\)\]))', '$1[assembly:AssemblyInformationalVersion("$3-alpha")]' } | Out-File $_.fullname }" 

我逃脱引号的标志尝试四周，命令中使用and &`但它没有帮助。

我错过了什么？

你有你的命令字符串中的双引号：

... -replace '((\[assembly:\sAssemblyVersion\(")(\d\.\d\.\d\.\d)("\)\]))', ... 
              ^    ^

这些必须进行转义为CMD：

... -replace '((\[assembly:\sAssemblyVersion\(\")(\d\.\d\.\d\.\d)(\"\)\]))', ... 
               ^^     ^^
