Hi, the Maven Stage Plugin and the Maven Verifier Plugin have been retired and are no longer maintained. We retired them because there was very little interest by and interaction with users over the past years: neither had been released in over ten years.
The retirement vote results can be seen here: https://lists.apache.org/thread/j0dqo61wlm7fxsrvgq0r718nzpjc1byk There is no final release. The last published versions remain maven-stage-plugin 1.0 and maven-verifier-plugin 1.1, and both stay available from Maven Central, so existing builds that reference them will keep working. Their source repositories have been archived and are now read only. If you would like to continue the development of either plugin, you can fork it using another groupId and artifactId. You also need to rename the plugin, for example from "maven-stage-plugin" to "stage-maven-plugin", because artifact ids with the "maven-" prefix are reserved for the Apache Software Foundation. Feel free to inform others that you continue working on the plugin in a different place. You can write a mail to the users mailing list for that. -The Apache Maven team
