After doing some project analysis in my company Sonarqube instance (7.9.4), the Debt Ratio measure always shows me 0.0% in projects with lot of technical debt like this:
This problem appears in large and shot projects, with SonarScanner and Sonar Maven analysis and all the projects have the sonar.scm.disabled = false property and all projects have git as SCM provider. In addition, all the analysis are running through Bamboo server and all git clone operations previous Sonarqube analysis are unshallowed clone operations.
In all the projects that have the 0.0% Debt Ratio value, in the analysis log appears the “Missing blame information” typical warning, but in other projects appears too this message but the Debt Ratio is calculated OK. An example of analysis log for a project with 0.0% Debt Ratio value is shown below:
Anybody knows what could be the bug or the problem in these analysis?? I would appreciate your answers.
Thanks in advance.
