[FATAL] pubspec.yaml does not exist in Monorepository

Problem

if you try to analyze the project in the root folder of the repository it will fail because the sensorContext is located from where the sonar-scanner is executed.

Temporary

A possible solution is to add the property
sonar.projectBaseDir property in the sonar-scanner properties, at least while it is set to support executions outside this context.
