Maven distribution misses JSession?

Hi, I am doing an upgrade from lucee 4.5 to 5.3. We use lucee as library in our web application. Everything compiles fine, but when starting tomcat, it complains it cannot find the class JSession. I checked the jar, and indeed, it is not there.

my pom depenency entry:


I tried to also include the core dependency:


That tries to doanload all kinds of unresolvable depencies making it fail my build. This could be because our local proxy, artefactory, is not doing its job properly of course, but I would like to know whether things should work the way I described, or that I am missing something else.

I cannot find any documentation on lucee and maven, other that this page, which seems outdated:

Any pointers on how to continue from here are very well appreciated.
