Hi,
We are aware that SonarLint for Command Line is not ready to replace the html/console report feature. We will work on that in the coming weeks to reach same level as other SonarLint flavors (ie have connected mode).
Then we'll still miss issue tracking (ie match current issues with issues of the previous analysis, in order to decide what are new/resolved issues and also to map previous status like won't fix or false positive). We are convinced we need the second part: issues marked as FP/WF on server side should stay muted in SonarLint as far as possible.
Regarding "new" issue flag, this part is more controversial, we are still discussing options.
BTW you can continue to use issues report if you need it. The feature will only be dropped when there will be a proper alternative, and should not be before 7.0 according to our deprecation strategy.
