    <!-- Be careful here, especially to not import BOMs as io.zipkin.zipkin2:zipkin has 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.zipkin2:zipkin. As Brave itself is indirectly used, this
         can be extremely confusing when people are troubleshooting library version assignments. -->
