Asp.net core “后出现ASP.NET 5 RC1生成错误”；“恢复后”；在VST上构建时

我正在尝试使用Visual Studio Team Services（又名Visual Studio Online）上提供的新生成系统在我的ASP.NET 5 RC1应用程序上执行

dnu还原

My
project.json
包含一个
postrestore
命令，如下所示：

"scripts": {
    "postrestore": [ "npm install", "bower install", "gulp clean", "gulp min" ]
}

#Requires -Version 3.0

param($vsoProjectName, $projectName, $buildConfiguration, $buildSourcesDirectory)

$VerbosePreference = "continue"
$ErrorActionPreference = "Continue"

&{$Branch='dev';iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1'))}
$globalJson = Get-Content -Path "$PSScriptRoot\global.json" -Raw -ErrorAction Ignore | ConvertFrom-Json -ErrorAction Ignore

if($globalJson)
{
    $dnxVersion = $globalJson.sdk.version
}
else
{
    Write-Warning "Unable to locate global.json to determine using 'latest'"
    $dnxVersion = "latest"
}

& $env:USERPROFILE\.dnx\bin\dnvm install $dnxVersion -r coreclr -arch x86 -Persistent

$dnxRuntimePath = "$($env:USERPROFILE)\.dnx\runtimes\dnx-coreclr-win-x86.$dnxVersion"

Write-Host "BuildSourcesDirectory: $buildSourcesDirectory"
Write-Host "Project Path: $PSScriptRoot\src\$projectName"
Write-Host "Publish output: $buildSourcesDirectory\$vsoProjectName\artifacts\bin\$buildConfiguration\Publish"

Write-Host "Print dnu version"

& "dnu" "--version"

Write-Host "Starting DNU restore on all projects"

 # run DNU restore on all project.json files in the src folder including 2>1 to redirect stderr to stdout for badly behaved tools
Get-ChildItem -Path $PSScriptRoot\src -Filter project.json -Recurse | ForEach-Object { & dnu restore $_.FullName 2>1 }

Write-Host "Finished DNU restore"

在执行
dnu还原后
我可以看到构建日志中重复出现了几次错误，内容如下：

2015-12-28T17:49:15.6910525Z###[错误]指定的路径、文件名或两者都太长。完全限定文件名必须少于260个字符，目录名必须少于248个字符。

如果我在本地开发人员机器上的命令行上执行
dnu还原
，我就不会遇到这个问题。
为什么在VSTS构建中会发生这种情况，我如何修复它

我的构建脚本如下所示：

"scripts": {
    "postrestore": [ "npm install", "bower install", "gulp clean", "gulp min" ]
}

#Requires -Version 3.0

param($vsoProjectName, $projectName, $buildConfiguration, $buildSourcesDirectory)

$VerbosePreference = "continue"
$ErrorActionPreference = "Continue"

&{$Branch='dev';iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1'))}
$globalJson = Get-Content -Path "$PSScriptRoot\global.json" -Raw -ErrorAction Ignore | ConvertFrom-Json -ErrorAction Ignore

if($globalJson)
{
    $dnxVersion = $globalJson.sdk.version
}
else
{
    Write-Warning "Unable to locate global.json to determine using 'latest'"
    $dnxVersion = "latest"
}

& $env:USERPROFILE\.dnx\bin\dnvm install $dnxVersion -r coreclr -arch x86 -Persistent

$dnxRuntimePath = "$($env:USERPROFILE)\.dnx\runtimes\dnx-coreclr-win-x86.$dnxVersion"

Write-Host "BuildSourcesDirectory: $buildSourcesDirectory"
Write-Host "Project Path: $PSScriptRoot\src\$projectName"
Write-Host "Publish output: $buildSourcesDirectory\$vsoProjectName\artifacts\bin\$buildConfiguration\Publish"

Write-Host "Print dnu version"

Write-Host "Starting DNU restore on all projects"

Write-Host "Finished DNU restore"

以下是执行postrestore时的日志部分：
