Re: maven-site-plugin and sisu-inject-plexus

Tamás Cservenák
Howdy,

my 5 cents:

Something is stale, very stale in there, as plexus-container-default was
abandoned about 10 (maybe 12?) years ago, and sisu "shim"
(sisu-inject-plexus) was created as the direct replacement (as functional
and as API).

If your project has Plexus "the old container" (plexus-container-default)
pulled in, it means something on project or it's transitive dependency hull
lags for about 10+ years if not more :)

Given Plexus is "maven only" (mostly), it is most probably that some
dependency (governed by us, chance is 90%+) pulls it in, that has not been
touched for quite a long time.

Plexus et al is one of the reasons why "maven pulls down the internet",
especially as we resolve/download it only to toss it away (drop it).
