Please download a database export to:
  ${db.load.export_pattern}.sql.gz

Alternatively, you can specify the export file prefix; for example:
  vendor/bin/phing [YOUR-TARGET] -Ddb.load.export_pattern=artifacts/prod-*

Or, you can specify the export file directly:
  vendor/bin/phing [YOUR-TARGET] -Ddb.load.file=artifacts/my_db.sql.gz
              </echo>
              <fail message="Missing database export." />
          </then>
        </if>

        <echo>Loading the `${db.load.file}` database...</echo>
        <exec dir="${build.dir}" command="gunzip -c ${db.load.file} | ${db.load.mysql_command}" checkreturn="true" logoutput="true" />
