NuGet Package missing error when trying to use TFS Servcice - tfs

Question

I'm hoping someone can help diagnose whats going wrong with my build. I'm using Visual Studio 2012, NuGet 2.7, & TFS Service (git). I've been unable to get around the following error:
"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."
I've enabled the package restore feature (but it think i've heard with nuget 2.7 it doesn't matter). Anyways i found a helpful blog about this problem at :
Blog Article
Here is my current build script:
<?xml version="1.0" encoding="utf-8"?>

So i copied his build log and just changed the path where nuget.exe is. Nuget.exe command seems to be running but apparently its not downloading the packages. Of course building locally works fine (even if i delete the packages directory.

Answer 1

As I can see in the link in the error message line you posted:
There is an improvement in Nuget 2.7 as below:
The Improvement
We’ve updated Microsoft.Bcl.Build to use a different approach. The
new version will use a conditional import similar to what NuGet’s
automatic import feature does. This will always allow the project to
load in Visual Studio.
However, Microsoft.Bcl.Build also adds a target to your project
that will run after the build is finished. This target checks whether
the current build restored packages and if so fail the build with an
actionable error message:
The build restored NuGet packages. Build the project again to include
these packages in the build. For more information, see
http://go.microsoft.com/fwlink/?LinkID=317568.
Building a second time will fix this error. Please note that this
error will only appear if packages were missing so it’s not like you
always have to build twice.
However, below that it says that it will not address build server/continuous integration (CI) scenarios and it needs a solution as specified in the following excerpt from the article:
This solution doesn’t address build server / continuous integration
(CI) scenarios. In order to successfully use package restore on the
build server, you have two options:
Check-in the .targets file.
Explicitly run NuGet package restore prior to building your project/solution.
Hope the issue you are facing is also because of this only.

For me the reference to Microsoft.Bcl.Build and the BeforeTargets="BeforeBuild" was causing problems. This got added when Microsoft.Bcl.Build was added as a dependency to an Azure Nuget package.
Try checking your project file and removing it.
<Import Project="..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets" Condition="Exists('..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" />
<Target Name="EnsureBclBuildImported" BeforeTargets="BeforeBuild" Condition="'$(BclBuildImported)' == ''">
<Error Condition="!Exists('..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" Text="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." HelpKeyword="BCLBUILD2001" />
<Error Condition="Exists('..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" Text="The build restored NuGet packages.
