Description

For all the 3.0 versions of the maven-plugins we require to not depend on maven-compat anymore. However, the Maven distribution still requires maven-compat. A simple proof: remove lib/maven-compat-3.x.y and execute mvn validate.
You'll get the following exception:

[WARNING] Error injecting: org.apache.maven.project.DefaultProjectBuildingHelper
com.google.inject.ProvisionException: Unable to provision, see the following errors:

1) No implementation for org.apache.maven.repository.RepositorySystem was bound.
  while locating org.apache.maven.project.DefaultProjectBuildingHelper

Reason: there's only one implementation: o.a.m.r.l.LegacyRepositorySystem, which is part of maven-compat.
