Using variables in appveyor.yml

Hi All

I am trying to get my head around building a .net core app (SDK 2.1) on AppVeyor, so far I have got 90% of the process bedded down, however I am struggling with publishing my package to NuGet - more specifically using variables in the appveyor.yml file, on this line:

after_build:
  - cmd: dotnet nuget push Rn.Common.1.0.{build}.nupkg -k {NuGetKey} -s https://www.nuget.org/

Ideally I would like it to substitute 2 variables here - (1) the build number to address the packaged NuGet file and (2) and environment variable I defined for the NuGet publish key. I have tried many different ways of escaping the variable and Googled the heck out of it with no luck.

Could someone please point me in the right direction here - it would be greatly appreciated.

P.S. presuming I get this right - would the API key be printed out in the build log?

e.g. https://ci.appveyor.com/project/rniemand/rn-common/builds/20917617

   For cmd: environment variables are accessed by surrounding variable name with %%.
   i.e. %build%, %NuGetKey%

   Thanks for that - I replaced the line in question with:

       - cmd: dotnet nuget push Rn.Common.1.0.%version%.nupkg -k %NuGetKey% -s https://www.nuget.org/

   But it didn't seem to work:

   cd bin/Release
   dotnet nuget push Rn.Common.1.0.%version%.nupkg -k %NuGetKey% -s https://www.nuget.org/
   error: File does not exist (Rn.Common.1.0..nupkg).
   Command exited with code 1

   Here's a list of environment variables set for every build. Version is not one of them, so unless you set it as an environment variable its not available. ...Perhaps you meant to use APPVEYOR_BUILD_VERSION.

   Thanks for that - I gave up on the venture because I was concerned of exposing my API key in the build log, and had a lot more success with a PowerShell script, namely:

   https://github.com/rniemand/Rn.Common/blob/master/appveyor.yml

   and

   https://github.com/rniemand/Rn.Common/blob/master/build/package.ps1

   Appreciate all the help!
