These CLI utilities are used to fetch things we need.

• SDKMan
• Coursier

We need a JDK, which SDKMAN is used for.

# List available JDKs
sdk ls java

Amazon seems to have a high-quality one.

• Amazon Coretto

Version 11 is the last LTS version.

• (sbt)[https://www.scala-sbt.org/index.html]

sdk i sbt 1.5.0

A system-wide build server that speeds compile times and can watch for changes and automatically recompile.

• (Bloop)[https://scalacenter.github.io/bloop/]

cs install bloop --only-prebuilt=true

Create a new Scala 3 project using the following template:

• scala3.g8

sbt new scala/scala3.g8

Change into your project directory and compile and run it using sbt.

sbt compile
sbt run

This extension will install everything it needs

• Metals

Use Bloop to watch for changes and automatically compile and run your program. Your project should have a .bloop directory that contains a <project>.json, <project>-test.json, and a <project> subdirectory. (Metals in VS Code will create this automatically.) If it doesn't exist, you'll need to use bloop project to create one.

In one terminal session from within your project's root directory (the one that contains .bloop), run:

bloop compile -w <project>

From another terminal (same directory), run:

bloop run -w <project>
