The Getting Started guide for Scala says:
Run the command
sbt new scala/scala3.g8
to create a Scala 3 project, orsbt new scala/hello-world.g8
to create a Scala 2 project.
Are there any more sbt new
templates available? Where do I find that list?
You can see at sbt docs, the section sbt new and Templates
Giter8 support
Giter8 is a templating project originally started by Nathan Hamblen in 2010, and now maintained by the foundweekends project. For more, see Giter8 templates on the Giter8 wiki.
There is a list with templates for different types of projects and libraries.
