Can i only build the single jar spark-core_2.11-2.3.2.jar? After finishing building the single jar then copy the jar to $SPARK_HOME/jars directory. If anyone knows the detail way to make it work, please tell me because i think it spends long time(20+ minutes in my windows laptop) to rebuild the whole package if only make small modification.
