Failed to load class in Spark-submit - scala

Question

I'm running a jar file with Spark-submit, but i keep getting this error:
Error: Failed to load class antarctic.DataQuality.
This is the command:
spark-submit --class antarctic.DataQuality --master local[*] --deploy-mode client --jars "path/to/file.jar" "arg 1" "arg 2" "arg 3" "arg 4"
This is the structure of the Scala file:
