  <dependencies>
    <!--
      This is a dummy dependency that is used to trigger the maven-shade plugin so that Spark's
      published POMs are flattened and do not contain variables. Without this dependency, some
      subprojects' published POMs would contain variables like ${scala.binary.version} that will
      be substituted according to the default properties instead of the ones determined by the
      profiles that were active during publishing, causing the Scala 2.10 build's POMs to have 2.11
      dependencies due to the incorrect substitutions. By ensuring that maven-shade runs for all
      subprojects, we eliminate this problem because the substitutions are baked into the final POM.

      For more details, see SPARK-3812 and MNG-2971.
