Running updated quality profile against existing projects in sonar qube

Question

I currently have a SonarQube instance setup with multiple projects. Currently I get multiple requests every few weeks to update the quality profile to include a new rule or to remove an old one. This is usually followed by me having to recreate the projects and then sequentially running analysis again so that I can have the differential view again starting from a baseline code. This is becoming a pain as the number of projects grow. Is there any alternative to this? For instance is there any way to tell Sonar to pick up the new rules from the quality profile and run the existing analysis again against these rules.

If I don't do that I get a spike in issues as new rules get added and a new analysis is run as the existing analysis wasn't run against those rules and doesn't have an accurate issue number.

Thanks for the help!

Answer 1

Once you have linked a profile to a project, you can change the rule set and it will be used during the next analysis. As you add or remove rules, spikes are normal. Propably what you want to ensure is that for example no new rules are introduced as you want to ensure the quality is not going down, but is always improved. You can do it using quality gates and build breaker plugin. Hopefully I could help.

Answer 2

I am not sure to understand very well what you want to do, if this is running again a new (changed) profile to all previous versions of a project, or to apply different profiles on different versions of a project.
