commit d2fd3bfa3b10f6fd76a6cd1a85a30f1ca4d774b7

    Verify the plugin on the oldest Maven the build allows
    
    The verify matrix runs current Maven only. One extra matrix entry runs the
    full build and ITs on Maven 3.9.0, the floor the ASF parent enforces, so
    API drift against the older 3.9 line is caught before a user hits it.
