尝试使用TFS Servcice时,NuGet Package丢失错误

Question

我希望有人可以帮助诊断我的构建出了什么问题.我正在使用Visual Studio 2012,NuGet 2.7和TFS服务(git).我一直无法解决以下错误:

"C:\a\src\src\RecipeDb.Mvc\RecipeDb.Mvc.csproj (361): This project references NuGet   package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=317567."

我启用了包恢复功能(但我认为我听说过nuget 2.7并不重要).无论如何,我发现了一个关于这个问题的有用博客: 博客文章

这是我当前的构建脚本:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0"
         DefaultTargets="Build" 
         xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

    <OutDir>$(MSBuildThisFileDirectory)bin</OutDir>
    <Configuration>Release</Configuration>
    <ProjectProperties>
        OutDir=$(OutDir);
        Configuration=$(Configuration);
    </ProjectProperties>
  </PropertyGroup>

  <ItemGroup>
    <Solution Include="$(MSBuildThisFileDirectory)src\*.sln" />
  </ItemGroup>

  <Target Name="RestorePackages">
    <Exec Command="&quot;$(MSBuildThisFileDirectory)src\.nuget\NuGet.exe&quot; restore &quot;%(Solution.Identity)&quot;" />
  </Target>

  <Target Name="Clean">
    <MSBuild Targets="Clean"
             Projects="@(Solution)"
             Properties="$(ProjectProperties)" />
  </Target>

  <Target Name="Build" DependsOnTargets="RestorePackages">
    <MSBuild Targets="Build"
             Projects="@(Solution)"
             Properties="$(ProjectProperties)" />
  </Target>

  <Target Name="Rebuild" DependsOnTargets="RestorePackages">
    <MSBuild Targets="Rebuild"
             Projects="@(Solution)"
             Properties="$(ProjectProperties)" />
  </Target>

</Project>

这是我的构建日志:

所以我复制了他的构建日志,只是改变了nuget.exe所在的路径.Nuget.exe命令似乎正在运行,但显然它没有下载软件包.当然在本地构建工作正常(即使我删除packages目录.

正如我在链接中看到的正如我在您发布的错误消息行的

\n\n

Nuget 2.7有如下改进：

\n\n

\n

改进

\n\n

我们\xe2\x80\x99 已更新Microsoft.Bcl.Build以使用不同的方法。新版本将使用类似于NuGet\xe2\x80\x99s\n 自动导入功能的条件导入条件导入。这将始终允许项目在 Visual Studio 中加载。

\n\n

但是，Microsoft.Bcl.Build还会向您的项目添加一个目标，该目标将在生成完成后运行。此目标检查当前构建是否恢复了包，如果是，则构建失败并显示可操作的错误消息：

\n\n

\n\n

构建恢复了 NuGet 包。再次构建项目以在构建中包含\n这些包。有关详细信息，请参阅\n http://go.microsoft.com/fwlink/?LinkID=317568。

\n\n

第二次构建将修复此错误。请注意，只有在缺少软件包的情况下才会出现此错误，因此它不像您总是需要构建两次。

\n\n

然而，下面它说它不会解决构建服务器/持续集成（CI）场景，它需要一个解决方案，如以下文章摘录中指定的：

\n\n

\n

此解决方案不解决\xe2\x80\x99t 构建服务器/持续集成\n (CI) 场景。为了在构建服务器上成功使用包还原，您有两个选择：

\n\n

\n
1. 签入 .targets 文件。
\n
2. 在构建项目/解决方案之前显式运行 NuGet 包还原。
\n

\n

\n\n

希望您所面临的问题也只是因为这个。
