Developing Spark applications in Eclipse with SBT

Simple Build Tool (SBT) is a build tool made especially for Scala-based development. SBT follows Maven-based naming conventions and declarative dependency management.

SBT provides the following enhancements over Maven:

• It provides a shell that makes it very handy to perform build operations
• For simple projects without dependencies, you do not even need the build.sbt file

In build.sbt, the first line is the project definition:

lazy val root = (project in file("."))

Each project has an immutable map of key-value pairs. This map is changed by settings in SBT like so:

lazy val root = (project in file(".")) ...
