    Description

      Version 3.6.1 of maven-plugin-plugin worked fine, but since updating to version 3.6.2, I get an NPE (tested with Java 8 and Java 17). I believe the error in both Java 8 and Java 17 is the same, but Java 17 gives a better message (see below).

      Even though it's the nexus-staging-maven-plugin that is complaining, the message implies that the maven-plugin-plugin is somehow failing to extract the prefix from the plugin. Going back to maven-plugin-plugin version 3.6.1 fixes the issue.
