That .nuspec file looks fine, but doesn't match the error message. The error message indicates that the .nupkg has a dependency on "JetBrains.ReSharper.SDK". ReSharper uses NuGet packages in a runtime capacity, so development dependencies shouldn't be included. When installing, ReSharper will try to resolve any dependencies and install them (as runtime extensions, not assembly references). The "JetBrains.ReSharper.SDK" package is a nuget assembly reference package, and isn't required, or available on ReSharper's extension package gallery, so it fails to install.
I'd suggest getting NuGet Package Explorer and double clicking on the .nupkg to see if it's got the same .nuspec as you've shown.
Also, you should be copying the *.dll
files into ReSharper\v8.2\plugins
. It can't live in vAny
because ReSharper plugins are compiled against specific versions of ReSharper. And it should only go in the vs12.0
folder if it's specific to Visual Studio 2013, i.e. it uses VS2013 assemblies and functionality.
