When you are building a dotnet core project with SonarQube you may be facing the error in the log:
WARNING: The following projects do not have a valid ProjectGuid and were not built using a valid solution (.sln) thus will be skipped from analysis...
What should you do?
As dotnet core projects (.csproj) will not have <ProjectGuid>...</ProjectGuid>
tag specified in the default template this needs to be manually added.
So you need to edit the .csproj file like this:
<PropertyGroup>
<!-- other properties here -->
<!-- SonarQube needs this -->
<ProjectGuid>{E2CEBBAF-6DF7-41E9-815D-9AD4CF90C844}</ProjectGuid>
Make sure to place your own GUID inside the <ProjectGuid>...</ProjectGuid>
