Hello, World 

This page assumes you’ve installed sbt 0.13.13 or later.

sbt new command 

If you’re using sbt 0.13.13 or later, you can use sbt new command to quickly setup a simple Hello world build. Type the following command to the terminal.

$ sbt new sbt/scala-seed.g8
Minimum Scala build.

name [My Something Project]: hello

Template applied in ./hello

When prompted for the project name, type hello.

This will create a new project under a directory named hello.

Running your app 

Now from inside the hello directory, start sbt and type run at the sbt shell. On Linux or OS X the commands might look like this:

$ cd hello
$ sbt
> run
[info] Compiling 1 Scala source to /xxx/hello/target/scala-2.12/classes...
[info] Running example.Hello

We will see more tasks later.

Exiting sbt shell 

To leave sbt shell, type exit or use Ctrl+D (Unix) or Ctrl+Z (Windows).

> exit

Build definition 

The build definition goes in a file called build.sbt, located in the project’s base directory. You can take a look at the file, but don’t worry if the details of this build file aren’t clear yet. In .sbt build definition you’ll learn more about how to write a build.sbt file.
