Spark Cassandra Connector Maven Build Issue - apache-spark

Question

Hi I am trying to write Spark application which reads data from Cassandra. My Scala version is 2.11 and Spark version is 2.2.0. Unfortunately I am facing build issue. It says "missing or invalid dependency detected while loading class file 'package.class'. I do not know what is causing this issue.
Here's my POM File

Any ideas what could be the problem?

Edit: I really missed that 1.5.0-RC1 was commented out...
It should be enough to specify cassandra-spark-connector dependency - it already has dependency on spark-core & spark-sql. But if you use Spark 2.x, you need to use 2.x version of cassandra-spark-connector (although it has dependncy on 2.0.2, it could work with 2.2.0).
I don't know where did you take version 1.5.0-RC1 - it's veeeery old...
