sonar begin fails on our build server (Bitbucket pipelines) with the following error:

Why does sonar begin require .NET Core 2.0.0?

Hi @farmadthomasdc , welcome to the community.

How are you pulling the Scanner for .NET within your pipeline ?

We’re using Cake which in turn uses NuGet Gallery | dotnet-sonarscanner 5.2.2

However, I found this related issue on github: https://github.com/SonarSource/sonar-scanner-msbuild/issues/797
The workaround mentioned on that page solves the issue. I had to add a new environment variable DOTNET_ROLL_FORWARD with value Major

Ok, glad it works then ! Because in this nuget we embed the .NET 5 version as well, so you might be able to use it.

Ok, interesting. How can I force the use of the .NET 5 version?

It’s done automatically depending on the version of the .NET CLI you use to run the Scanner.
