Trying to build the project errors out here. Am I missing something?

Attempting to gather dependency information for package 'gitversion.commandline.3.5.5-pullrequest0921' with respect to project 'packages', targeting 'Any,Version=v0.0'
Package 'gitversion.commandline,3.5.5-pullrequest0921' is not found in the following primary source(s): 'C:\Users\shiftkey\AppData\Local\NuGet\Cache,C:\Users\shiftkey.nuget\packages,https://api.nuget.org/v3/index.json,C:\Program Files (x86)\Microsoft SDKs\NuGetPackages'. Please verify all your online package sources are available (OR) package id, version are specified correctly.

EDIT: how are my feeds different to what's on Appveyor? Hrm.

[clairernovotny]

It should be using the Build Packages feed with the guid in it.... That's where I put that package while I wait for it to be officially merged and published.

@onovotny I think this is related to where you execute the build-new scripts from.

On my machine, when .\build then executes .\Rx.NET\Source\build-new the location isn't changed, so it:

• checks and downloads nuget.exe to root of the repository
• nuget restore ... doesn't resolve a nuget.config at the root
• it misses the additional Build Packages feed, so it can't find this new package

The workaround I tested was to do this:

Push-Location ".\Rx.NET\Source\"
Write-Host "Building Rx.NET" -ForegroundColor Green
.\build-new
Pop-Location

There's probably a much cleaner way to do this (avoiding duplicate downloads of nuget.exe in particular), but I also haven't looked into why Appveyor isn't failing in the same way...

[clairernovotny]

@shiftkey there's a nuget.config at the root here that should work https://github.com/Reactive-Extensions/Rx.NET/blob/master/NuGet.Config. Was that not getting picked up for you?

[shiftkey]

💄 indenting (lol)

[clairernovotny]

bah, I'll fix it -- was a merge conflict, so VS didn't generate that.

[shiftkey]

Was that not getting picked up for you?

It was not, but let me have another shot at it now...

[shiftkey]

Build script is fine now on my machine, I just can't create packages:

Looking at the diff for the generated AssemblyInformationVersion entry, it seems like GitVersion is being very verbose:

-[assembly: AssemblyFileVersion("2.2.0.0")]
-[assembly: AssemblyInformationalVersion("2.2.0.0")]
+[assembly: AssemblyFileVersion("3.0.1.0")]
+[assembly: AssemblyInformationalVersion("3.0.1-assembly-versions.27+Branch.assembly-versions.Sha.ab35480481315a6703909afab95b4fb769b6d898")]

Do we care about this constraint?

[shiftkey]

After a fresh build there are two changes to dependencies:

• Rx.NET/Source/NuSpecs/Microsoft.Reactive.Testing.nuspec bumps xunit.assert from v2.1.0 to 2.2.0-beta2-build3300
• Rx.NET/Source/NuSpecs/System.Reactive.Observable.Aliases.nuspec adds System.Resources.ResourceManager v4.0.1

Want to pull those in here?

[shiftkey]

@onovotny just a few little things - would love to be able to poke the packages and verify the changes but I won't hold that up because of how GitVersion names branches in this situation...

[clairernovotny]

Yeah, I wouldn't worry about any package failures due to branch names. I wish NuGet didn't have that limit; otherwise, I can also look into ways to truncate to fit. Prob another PR.

[clairernovotny]

As for versions of BCL refs, I'm going to create a separate PR to remove those granular deps and just reference NETStandard.Library. That's the new/current recommendation of the NuGet/BCL team.

[shiftkey]

@onovotny 👍

[clairernovotny]

As for the xunit.assert version, #210 will turn that into a source reference, internal, so that dependency will go too.
