We recently migrate from OSSHR (which reach End of Life) to Maven Central :

• Migrate from OSSHR (which reach End of Life) to Maven Central for master #1735
• Migrate from OSSHR (which reach End of Life) to Maven Central for branch 1.x #1742

But after some exchange with sonatype, central-publishing-maven-plugin license is very unclear.
See more details at : eclipse-cbi/central-staging-plugins#5

I just open this issue to keep in mind that we keep an eye on that.
Meaning watch if sonatype will really clean that license mess OR if we should migrate to an alternative like eclipse/central-staging-plugins
