Spark Maven fail to find ml classes - scala

Question

I create code spark with SparkSession but i can't run this code.
I think I am missing some dependencies in my pom.xml or something else-
import org.apache.spark.sql.SparkSession
val spark = SparkSession
.builder
.appName("loader")
.master("local")
.getOrCreate()
pom.xml for scala 2.11
