I know i can add the jar in my project and i can use it, but that's something i don't want to do. I need to use the source code of core Module which we have in the spark_parent_2.12 on github.
I am able to extract the core project from the spark and add it into my project as dependency here is my pom.xml.

I am able to access org.apache.spark.SparkConf or SparkContext but i am not able to access org.apache.spark.annotation.DeveloperApi in the Aggregator.scala file.
any help will be much appreciated.

Answer 1

You should add spark-tags dependency :
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-tags_2.12</artifactId>
<version>2.4.3</version>
</dependency>
