which versions are you using (SonarQube, Scanner, Plugin, and any relevant extension)
what are you trying to achieve
I want to confirm whether or not providing a full repo coverage report is necessary or required when running a scan for the main branch of that repo? If you don’t, what would the expected result be? Would it mess up the current reported coverage for main?
Yes, a full coverage report must be provided, otherwise you will only see coverage reported for what’s included in the coverage report you pass (not representative of your main branch)
Make sure you upgrade to SonarQube v9.9 LTS soon, not only to benefit from our Best LTS Ever™, but because soon we will systematically ask users to upgrade when they ask questions about earlier versions of SonarQube, which are now considered unsupported.
