What are AssemblyKeys used for, and how to import them?

Question

In a recent popular sbt app https://github.com/databricks/reference-apps, I found a line that required me to

import AssemblyKeys._ 

This line doesn't compile in SBT or in my IntelliJ IDEA.

What is the import used for and why is it necessary?

Answer 1

With the latest version, we no longer need to import the AssemblyKeys._
