Change default Scala versions to 2.13.18 and 2.12.21

This Scala CLI version switches the default Scala versions:

  • default Scala 2.13 to 2.13.18
  • default Scala 2.12 to 2.12.21

Added by @Gedochao in #3999 and #3958

Fall back to a legacy version of the runner & test-runner modules for JVM < 17

The newest versions of the runner and test-runner modules will require Java 17 or newer to run.
When trying to use them with older JVMs, Scala CLI will now print a warning and fall back to using legacy versions of those modules instead.

scala-cli test . --jvm 11
# Compiling project (Scala 3.7.4, JVM (11))
# Compiled project (Scala 3.7.4, JVM (11))
# [warn] Java 11 is no longer supported by the test-runner module.
# [warn] Defaulting to a legacy test-runner module version: 1.7.1.
# [warn] To use the latest test-runner, upgrade Java to at least 17.

Added by @Gedochao in #3965

v1.10.0

Change default Scala versions to 3.7.4 and 2.13.17

This Scala CLI version switches the default Scala versions:

  • default Scala 3 to 3.7.4
  • default Scala 2.13 to 2.13.17
scala-cli version
# Scala CLI version: 1.10.0
# Scala version (default): 3.7.4

Added by @Gedochao in #3942 and #3895

Support for the new Scala 3.8 REPL

As per scala/scala3#24243, Scala 3 REPL has been extracted to a separate artifact in Scala 3.8, as a result of which the use of the REPL command with Scala 3.8.0-RC1-bin-20251101-389483e-NIGHTLY or newer will require upgrading Scala CLI at least to 1.10 to work.

scala-cli repl                                          
# Welcome to Scala 3.8.0-RC1-bin-20251101-389483e-NIGHTLY (23.0.1, Java OpenJDK 64-Bit Server VM).
# Type in expressions for evaluation. Or try :help.
#                                                                                                                  
# scala>

Added by @Gedochao in #3936

Support for adding extra directories to a Docker image

This feature adds the ability to include additional directories in Docker images. Users can now specify extra directories to be copied into a Docker image during the build process. The directories can be passed with the --docker-extra-directories command line option or //> using packaging.dockerExtraDirectories directive.

//> using packaging.dockerExtraDirectories path/to/directory1 path/to/directory2
scala-cli --power package . --docker --docker-image-repository repo --docker-extra-directories path/to/directory

Added by @btomala and @Gedochao in VirtusLab/scala-packager#250 and #3908

Deprecate support for building GraalVM native images with Scala pre-3.3

When building GraalVM native images with Scala CLI and Scala versions older than 3.3.0, the following warning will now be printed:

# [warning] building native images with Scala 3 older than 3.3.0 is deprecated.
# [warning] support will be dropped in a future Scala CLI version.
# [warning] it is advised to upgrade to a more recent Scala version

While the native images will still be built, the functionality will be removed in a future Scala CLI version. It is advised to migrate projects to Scala 3.3 or newer.

Additionally, the following modules have been dropped and will no longer be published:

  • scala3-runtime
  • scala3-graal
  • scala3-graal-processor

As they remain necessary for building native images for Scala pre-3.3 projects, their usage has been deprecated and frozen at respective version 1.9.1.

Added by @Gedochao in #3929

Stop publishing certain modules for Scala 2

While it is technically an internal change, it is worth noting certain Scala CLI modules will no longer be published for Scala 2.
Those include:

  • runner
  • test-runner
  • tasty-lib
  • config
  • specification-level

From this point on, they will only be published for Scala 3.

Added by @Gedochao in #3911 and #3912

Features

  • Ensure non-self executable JVM launchers' setup-ide produces working BSP connection JSON by @Gedochao in #3876
  • Fix test scope resources to not be added to the main scope by @Gedochao in #3898

Support for the new Scala 3 nightly repository

This Scala CLI version supports the new Scala 3 nightly versions repository:

https://repo.scala-lang.org/artifactory/maven-nightlies

This means that newest Scala 3 nightly versions will become available to use with Scala CLI, as well as the 3.nightly tag will now refer to the actual, newest version.

As a result, Scala 3.8 features like capture checked Scala 3 library should now be available from Scala CLI.

//> using scala 3.8.0-RC1-bin-20250901-ca400bd-NIGHTLY
import language.experimental.captureChecking

trait File extends caps.SharedCapability:
  def count(): Int

def f(file: File): IterableOnce[Int]^{file} =
  Iterator(1)
    .map(_ + file.count())

Added by @Gedochao in #3838

Support for Scala 3.7.2

This Scala CLI version switches the default Scala version to 3.7.2.

scala-cli version
# Scala CLI version: 1.8.5
# Scala version (default): 3.7.2

Added by @Gedochao in #3809

Add props with input paths for non-script inputs

2 new properties have been added, to provide a way to access input paths outside of .sc scripts:

  • scala.sources - full paths of all inputs in the project, separated by java.io.File.pathSeparator
  • scala.source.names - names of all inputs in the project, separated by java.io.File.pathSeparator
//PrintSources.scala
@main def main() = {
  println(sys.props("scala.sources"))
  println(sys.props("scala.source.names"))
}
~/PrintSources.scala
PrintSources.scala

These are meant to be an input type agnostic equivalent for the scriptPath method available in .sc scripts.

Added by @philwalk in #3799

sonatype:snapshots points to the new Sonatype Central snapshots repository

It is no longer necessary to manually add https://central.sonatype.com/repository/maven-snapshots, it is added under the sonatype:snapshots alias (along with the old snapshot repository).
It is also added in all other contexts when snapshots should be used.

//> using repository sonatype:snapshots

Added by @Gedochao in #3797

Scala CLI nightlies are available again

We once again publish Scala CLI nightlies. You can use the newest version under the nightly tag.
As pre-1.8.5 Scala CLI versions do not look for them on the new Sonatype Central snapshots repository, they will not be visible when called from earlier versions.

scala-cli --cli-version nightly version
# Scala CLI version: 1.8.4-24-g8ca6c960b-SNAPSHOT
# Scala version (default): 3.7.2

Note that the new Sonatype Central Portal retains snapshot versions for 90 days, so individual versions will be available to test for a limited time period.

Added by @Gedochao in #3818

Features

  • Automatically add the new Sonatype Central Portal snapshots repository when snapshots are expected to be used by @Gedochao in #3797
  • Adjust Scala CLI nightly version resolution for the new Maven Central Snapshots repository by @Gedochao in #3818
  • provide a way to access paths of source files by @philwalk in #3799
  • Add more logging for publishing by @Gedochao in #3813

Fixes

Build and internal changes

  • Tag tests relying on old snapshots as flaky (or remove them where applicable) by @Gedochao in #3817
  • Add --no-fallback to graalvm native-image configuration by @lbialy in #3820

(⚡️ experimental) publish support for the Sonatype Central Portal

This Scala CLI version adds support for publishing artifacts to the Sonatype Central Portal via its OSSRH Staging API.
It is once again possible to publish artifacts to Maven Central with Scala CLI.
Both stable and *-SNAPSHOT versions are handled.
The only configuration change necessary is to migrate the Sonatype namespace in the UI and regenerate credentials to the new Sonatype Central Portal, as per Sonatype instructions

scala-cli publish . --power

Added by @Gedochao in #3774, #3776, #3778, coursier/publish#128 and coursier/publish#127

Better support for the REPL with JDK 24+

When using the REPL with JDK 24 or newer, users should no longer see the warnings about restricted methods of java.lang.System being used.

scala-cli repl --jvm 24
# WARNING: A terminally deprecated method in sun.misc.Unsafe has been called
# WARNING: sun.misc.Unsafe::objectFieldOffset has been called by scala.runtime.LazyVals$ (file:/Users/pchabelski/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/org/scala-lang/scala3-library_3/3.7.1/scala3-library_3-3.7.1.jar)
# WARNING: Please consider reporting this to the maintainers of class scala.runtime.LazyVals$
