Version

The version sub-command prints the currently used Scala CLI version and the associated Scala version.

scala-cli version

Scala CLI version: 0.1.19
Scala version (default): 3.2.1

It is also possible to print the same output with the -version option passed to the default sub-command. This way doesn't allow to use the other options relevant to version, however.

scala-cli -version

Scala CLI version: 0.1.19
Scala version (default): 3.2.1

When version is called, Scala CLI will automatically check if it's up to date. If your version is outdated, you will get a warning.

Your Scala CLI. version is outdated. The newest version is 0.1.19
It is recommended that you update Scala CLI through the same tool or method you used for its initial installation for avoiding the creation of outdated duplicates.

You can skip checking if Scala CLI is up to date by passing the --offline option.

scala-cli version --offline

It's also possible to just print the raw Scala CLI version with the --cli-version option. This won't check if the app is outdated, so the --offline option is unnecessary in this context.

scala-cli version --cli-version

0.1.19

note

Do not confuse the version sub-command's --cli-version option with the launcher option under the same name, as they do different things. The former prints the raw Scala CLI version, while the latter allows to change the Scala CLI launcher version. In fact, both of them can be used at one time.

scala-cli --cli-version 0.1.18 version --cli-version

0.1.18

Launcher options have to be passed before the sub-command is specified, which allows to differentiate between them.

Similarly, it's possible to just print the raw default Scala version. Once more, this won't check if the app is outdated, so the --offline option is unnecessary in this context as well.

scala-cli version --scala-version

3.2.1
