Regression possibly caused by MENFORCER-281

I have a multi-module project, the parent pom of which inherits from spring-boot-starter-parent. It also enables maven-enforcer. The Sprint Boot pom defines explicit versions for all of these plugins:

• org.apache.maven.plugins:maven-clean-plugin
• org.apache.maven.plugins:maven-failsafe-plugin
• org.apache.maven.plugins:maven-dependency-plugin
• org.apache.maven.plugins:maven-install-plugin
• org.codehaus.mojo:versions-maven-plugin
• org.apache.maven.plugins:maven-deploy-plugin

This worked fine under 3.0.0-M1. However, since 3.0.0-M2, I get the following build failure from maven-enforcer:

[WARNING] Rule 0: org.apache.maven.plugins.enforcer.RequirePluginVersions failed with message:
