This doc page is specific to features shipped in Scala 2, which have either been removed in Scala 3 or replaced by an alternative. Unless otherwise stated, all the code examples in this page assume you are using Scala 2.Introduction
The Scala compiler scalac offers various compiler options, or flags, that change the compilerâs default behavior. Some options just generate more compiler output in the form of diagnostics or warnings, while others change the result of compilation.
The Scala command scala, which runs scripts or compiled code, accepts the same options as the scalac compiler, plus a few more that determine how to run a program.
Options may be specified on the command line to scalac or in the configuration of a build tool or IDE.
The Scala distribution includes a man page. If Scala is installed as a system command, that documentation may be available from man scalac.
scalac [ <options> ] <source files>
Boolean flags are specified in the usual way:
scalac -Werror -Xlint Hello.scala
Options that require arguments use âcolonâ syntax:
scalac -Vprint:parser,typer
Options that take just a single argument accept traditional syntax:
scalac -d /tmp
Conventionally, options have a prefix -V if they show âverboseâ output; -W to manage warnings; -X for extended options that modify tool behavior; -Y for private options with limited support, where Y may suggest forking behavior. Several options have historical aliases, such as -Xfatal-warnings for -Werror.
In Scala 2, default paths can be listed by running a tool in the distribution:
scala scala.tools.util.PathResolver [ <options> ]
That can help debug errors in options such as --classpath.
Here is a typical configuration of the scalacOptions setting in sbt:
scalacOptions ++= Seq( // use ++= to add to existing options
"-encoding", "utf8", // if an option takes an arg, supply it on the same line
"-feature", // then put the next option on a new line for easy editing
"-language:implicitConversions",
"-language:existentials",
"-unchecked",
"-Werror",
"-Xlint", // exploit "trailing comma" syntax so you can add an option without editing this line
) // for "trailing comma", the closing paren must be on the next line
The convention is always to append to the setting with ++= and to supply one option per line.
Normally the last option will have a trailing comma so that git diff is a bit cleaner when options are added.
A set of standard options that are supported on the current development environment and will be supported in future releases.

Applications or libraries targeting the JVM may wish to specify a target version.
The -release option specifies the target version, such as â8â or â18â.
Like the option for javac, it allows building against an earlier version of the JDK. It will compile against the API for that version and also output class files for that version.
The deprecated option -target does not compile against the desired API, but only specifies a target class file format.
