Local environment setup

In this chapter, we are going to look at some of the tools that the rest of the book will use.

The build tool

We will be using sbt as the build tool. It was the first build tool that was specifically created for Scala. sbt uses a standard project directory structure underneath the main project directory, also called the base directory in sbt parlance. For example, if we created a project named hello in the /tmp/foo directory, then /tmp/foo is the base directory of the project. Here is what a typical directory structure will look like under the base directory:

build.sbt
project/
src/
-- main/
   |-- java/
   |-- resources/
   |-- scala/
|-- test/
   |-- java/
   |-- resources/
