It builds locally for me.
If there is no opposition, I would like to merge and release it today

[dependabot-preview]

OK, I won't notify you again about this release, but will get in touch when a new version is available.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.

[jglick]

It builds locally for me.

Including the -Prun-plugin-pom-its? OK. I filed INFRA-2197 to track.
