Why is dotnet build not using the specified SDK on global.json? - .net-core

Question

I have a global.json with the following contents
{
"sdk": {
"version": "2.2.300"
}
}
This is the output of dotnet --list-sdks
2.0.3 [C:\Program Files\dotnet\sdk]
2.1.105 [C:\Program Files\dotnet\sdk]
2.1.300 [C:\Program Files\dotnet\sdk]
2.2.300 [C:\Program Files\dotnet\sdk]
This is the output of donet --list-runtimes
Microsoft.AspNetCore.All 2.1.0 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.2.5 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.App 2.1.0 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.2.5 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.NETCore.App 2.0.3 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.0.7 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.0 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.2.5 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Yet when I do dotnet build I get the following error
Microsoft (R) Build Engine version 16.1.76+g14b0a930a7 for .NET Core

I need help, this is driving me nuts

Answer 1

Ok, found the solution, it seems this Environment System Variable
MSBuildSDKsPath was pointing to the .NET Core 2.1.300 Sdks folder, removing that variable addressed the problem.
