I just sync\'d an artifact to Maven Central from oss.sonatype.org. Immediately after doing so, a problem was discovered (of course). I haven\'t announced the new artifact
Can't be done. It's A Rule. But if you want to try, contact the Sonatype people who support oss.sonatype.org. So you generally push a new, higher, version with the fix, and tell everyone to use it.
