I believe the final required step is getting the build signed and the update site published.
I would agree that the WB project is completely dysfunctional due to lack of viable committers, and it does make the community look bad. For a project that is well used, no one (until just recently) has been interested in providing any help. I have asked for new committers many times over the years as our existing resources dwindled with no interest whatsoever. The project finally "broke" when we lost our Google-based build infrastructure and our build guy effectively stepped down. That meant we had no way to create a new build at all. Fortunately, Lars stepped up to create a new Tycho based build and became our first new committer in 5+ years (Thank you, Lars!!). That build had to pretty much be created from scratch and that has put an enormous burden on Lars' time. Getting some of the more difficult parts done (like the signing) have been difficult and required new Eclipse.org based infrastructure to be set up.
In the end once the new build is completely set up and automated, the project will be much better off at least in the sense that it will have a current build that will track bug fixes and Eclipse releases. The project is still extremely light on active committers and no one is actively working on the code itself. It has basically been in long term maintenance mode simply to support those Java IDE users who expect it to be there. New functionality has not been added for years although the existing functionality continues to work pretty well. A couple of the committers have some limited availability to fix critical bugs but that is about it. The project very much needs new committers interested in taking the project forward.
Lars can chime in with anything he needs specifically to keep this moving forward (and once again, thank you, Lars, for coming to WB's rescue!!).
I will also reiterate my plea to the community for folks interested in working on the project. Without new committers, WB will stay in long term keep-the-lights on mode with only critical bug fixes applied and no new functionality.
