Example sbt project that compiles using Scala 3
Usage
This is a normal sbt project. You can start the sbt shell using sbt then compile code with compile, run the main
method with run, run the tests with test and start a REPL using console.
If compiling this example project fails, you probably have a global sbt plugin
that does not work with Scala 3. You might try disabling plugins in
~/.sbt/1.0/plugins and ~/.sbt/1.0.
Making a new Scala 3 project
The fastest way to start a new Scala 3 project is to use one of the following templates:
Using Scala 3 in an existing project
You will need to make the following adjustments to your build:
project/build.properties
sbt.version=1.8.3
You must use sbt 1.5.5 or newer; older versions of sbt are not supported.
build.sbt
Set the Scala 3 version:
scalaVersion := "3.2.2"Getting your project to compile with Scala 3
For help with porting an existing Scala 2 project to Scala 3, see the Scala 3 migration guide.
