You can try this https://spark.apache.org/docs/latest/building-spark.html#building-submodules-individually Thanks, Gerry From: zhangliyun <kelly...@126.com> Sent: 2019年3月26日 16:50 To: dev@spark.apache.org Subject: How to build single jar for single project in spark Hi all: I have a question when i modify one file in spark project like org/apache/spark/sql/execution/ui/SparkPlanGraph.scala. 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.
