Less file looks good, thanks @bjagg!

In an unrelated turn of events, the jquery webjar seems to have gone missing from maven central?

That is a very very old version. Maybe it's time to remove it?

Restarted CI again this morning to see if it was a temporary resolution issue. ♻️

Also started a redeploy of jstree on webjars to see if that will help 🏗️

ideally yes.
Though this is a transitive dependency, through jstree, we'd need to wait for an upgrade there (which may be a bit, the author is recovering from an injury according to the project readme), or replace jstree with another library.

In my context I'm using custom web-components in place, because in several case we need only small component or a component with few features so which is really small. For complexe case we can find and use library for that.

Yay -- it passed!
