    <!-- Be careful here, especially to not import BOMs as io.zipkin.reporter2:zipkin-reporter and
         zipkin-reporter-brave have this parent.

         For example, if you imported Netty's BOM here, using Brave would also download that BOM as
         it depends indirectly on io.zipkin.reporter2:zipkin-reporter-brave. As Brave itself is
         indirectly used, this can be extremely confusing when people are troubleshooting library
         version assignments. -->
