AppHarbor not restoring packages - appharbor

Question

I'm pushing a NancyFx solution to AppHarbor, but it fails to build since AppHarbor isn't restoring the packages.
Package restore is defined in my solution file though.
Project("{2150E333-8FDC-42A3-9474-1A3956D46DE8}") = ".nuget", ".nuget", "{313EB245-8733-45FC-82B3-6C1404446A50}"
ProjectSection(SolutionItems) = preProject
.nuget\NuGet.Config = .nuget\NuGet.Config
.nuget\NuGet.exe = .nuget\NuGet.exe
.nuget\NuGet.targets = .nuget\NuGet.targets
EndProjectSection
EndProject
Here is a relevant piece of the AppHarbor log.

Anyone having an idea what's missing?

Answer 1

Is there a section in the csproj that references the NuGet.targets file? What you have just shows the items in the solution, the project needs a reference to the targets file to actually know what to execute upon build of a project.
The NuGet support isn't really anything special that MSBuild/VS knows about it (though VS does have an extension to make some things easier). The stuff (which should be inserted if you use the VS extensions "Enable Package Restore" functionality) is what tells MSBuild it needs to run an external command during build, which is what then restores the packages :-)
