Hi Benoit,
Thanks for the clarification.
My understanding is that by removing the modules we effectively render the
reporting configuration useless ( few useful reports will be generated )
I spent the evening playing around and there are several issues :
- jxr-plugin need to be configured to use the no-fork goal (this requires
running the clean package site instead of just site but avoids the weird
symbol resolution issues)
- some plugins are outdated and trigger an unsupported operation exception
when trying to access the security manager which is deprecated in newer jdk
versions
- apache-rat-plugin, versions-maven-plugin could be updated and resolved
the issue
- findbugs-maven-plugin seems to be abandonned (last release 2017) and
could not be updated. It seems to have been superseded by spotbugs but the
major version differs so I didn't attempt the upgrade and disabled the
corresponding report
- the javadoc plugin still causes some issues whether using the no-fork
variant or not so I also disabled it for now

with these changes the site generation goes much further.
it now fails on the mpt maven plugin's site generation with a similar error
to what happens in the main reactor

This seems related to some kind of reproductible build issue, the javadoc
suggests defining project.build.outputTimestamp
such as
-
<project.build.outputTimestamp>2023-01-01T00:00:00Z</project.build.outputTimestamp>
on the main build it still fails quite fast with unresolved symbols errors
event with no fork \o/

I launched the build again withouth javadoc reporting but it's late so I'll
know tomorrow morning as it takes a while to reach the mpt maven plugin.
cheers,
