Jenkins CI is skipping packages on nuget.exe restore my.sln
Oh my, do I feel like a rookie. Some of the packages were unintentionally committed to git. So when pulling sources from git, it also created a package folder with two packages in there. Which caused nuget restore to skip those as they already existed. It would have been very helpful if the output of nuget restore was to indicate that is was skipping package download in some form. Could have saved me hours!
