When you run your project in the next step, the configuration in build.sbt will be used to run the code in src/main/scala/Main.scala. When prompted to do so, select Import build.

Next, open the directory containing a build.sbt file (this should be the directory hello-world if you followed the previous instructions).

Install the Metals extension from the Marketplace.

Let’s take a look at what just got generated:.

When prompted, name the application hello-world.

It will also create a target folder, which you can ignore. This pulls a project template from GitHub.

Run the command sbt new scala/scala3.g8 to create a Scala 3 project, or sbt new scala/hello-world.g8 to create a Scala 2 project.

(It can also publish libraries and do many other tasks.) sbt compiles, runs,Īnd tests your Scala code. If you are familiar with the command line, we recommend that approach. To create a project, you can either use the command line or an IDE. Once you have installed sbt, you are ready to create a Scala project, which

if you don’t have Java 8 or 11 installed, download.

You only need two tools to compile, run, test, and package a Scala project: Java 8 or 11,
