def main(args: Array[String]): Unit = {

val conf = new SparkConf().setMaster("local").setAppName("My First Spark Program")

val sc = new SparkContext(conf)

Have you tried compiling by hand, then running (`scalac name.scala`, then `scala name`)? — serv-inc, Jan 17 '19 at 15:13

I guess it has something to do with your Build Configuration. It's hard to tell without further details.

Try to specify your main class in your project build configuration.
