SonarQube: How to configure leak period start ever

Question

I'm Using SonarQube 5.6.5 and trying to configure it so that the Leak Period is starting every x (=21) days.

Our sprints are running 21 days so I want the differential view is showing the changes since last sprint start. I get this only if I manually change each sprint start the 'Leak Period' to the date of the sprint start. Is there a more convenient way to do so?

Answer 1

Fixing the Water Leak (paradigm at the core of SonarQube features/UX) is about making sure that your software quality does not degrade from one product version to another, which is why the default value of the Leak Period is since_previous_version.

By definition of a sprint, your software should be releasable at the end of each sprint. If you do release an increment at each sprint then the default since_previous_version will do.

And actually even if you don't release every sprint, since_previous_version still is the best pick:

• quality since last released version is what you should focus on (if you didn't release after the previous sprint, then you shouldn't ignore bugs/vulnerabilities/code_smells potentially introduced back then)
• it will still ensure that quality does not degrade in the course of one sprint (since_previous_version being a sort of superset of 'since last sprint')
