unsure re Maven, 4.0.0 has been around the corner for years, but I think there is space for a modern alternative that is JPMS first, supports semantic versioning (i.e. tilde/carat notation) with lockfiles, and doesn't require a bunch of plugins out of the box for common use-cases. Maybe Mill (https://mill-build.org) - i've yet to try it.
Mill looks kind of nice on the surface but I haven't seen it in action in any serious project. I suspect the flexible DSL might come with a maintenance burden.
XML is nice, if your pom.xml is massive, just suck it in through JAXB and program against it, perhaps render it to a web page. XSLT can also be helpful. We're not supposed to look at XML as plain text.
