Description

To work on a PR for a documentation issue I noticed that build the master branch including site and site's reports via

mvn clean verify site -P reporting

results in a NPE

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.12.1:site (default-site) on project maven-dependency-plugin: Error generating maven-plugin-report-plugin:3.12.0:report report: Cannot invoke "org.codehaus.plexus.configuration.PlexusConfiguration.getChild(String)" because "this.configuration" is null -> [Help 1]
