Now that I’m actually looking at this, I see that you’re saying this is a revival of a “disappeared” plugin. In fact, I guess this is the old/original version?
guavamigration wasn’t actually (entirely) removed from the Marketplace. It looks like it just dropped out of the Plugin Version Matrix because there are no plugin versions compatible with current SonarQube versions.
Rather than making both of us jump through the hoops of adding a new plugin… surely you want to just issue a PR for your existing plugin entry? BTW, its entry did get dropped from this list, so you’ll want to make sure your PR includes reinstating it.
With deep apologies for my inexcusable lateness,
