I'm using a build with these commits. The scanner is triggered but no "licenses.json" files are found.

We are probably missing some documentation on how to add the licenses file to sonar scanner.

I'm using dotnet-project-licenses to generate the licenses file.

The command: dotnet-project-licenses -j -u -i . - json output; uniq license registry; project root.

The file is well generated but there is no detection on sonar scanner. Verbose output available below.
