Welcome back.

Looks like someone has hooked you up—Slack telling me email@hidden

There are several. There's a #maven channel on Slack.

Before we wade into these, how did you convert your project(s) to Maven? Did
you follow this or something like it?

I would suggest doing one project at a time. Choose a framework that is
dependent on no other projects, for example. Get it working, then move to the
next.

You won't regret it. Any time you spend now getting your projects converted
will be paid off a hundred times later. It will instantly simplify your CI
options, just as one example.
