How to create jar file from spark scala file?

[#1]

I think that the best option for compiling scala Spark code is to use sbt,which is a tool for managing dependencies. You can do the same with Maven anyway, as you prefer.

See http://spark.apache.org/docs/latest/quick-start.html#self-contained-applications "Self-Contained Applications" for all languages

Though there are many ways to do that but you can use sbt tool to build your application jar, below is a good example doc to build a jar and run it on spark

In case you are looking for a Maven project to build Spark/Scala. Here is an example https://github.com/vinayshukla/SparkDemo1

Note it was for Spark 1.1.0 but you can change the version.
