Although the semantic versioning plugin version 1.11 has been releases, it does not show up in the Update Center: https://updates.jenkins.io/current/update-center.actual.json

The release does not show up in the maven repo: https://repo.jenkins-ci.org/releases/org/jenkins-ci/plugins/semantic-versioning-plugin/

Obsolete parent POM and no distributionManagement override means the repo URL is wrong. These releases don't get uploaded.
