Package org.gradle.api.tasks
Class ScalaRuntime
java.lang.Object
org.gradle.api.tasks.ScalaRuntime
Provides information related to the Scala runtime(s) used in a project. Added by the
org.gradle.api.plugins.scala.ScalaBasePlugin as a project extension named scalaRuntime.
Example usage:
plugins {
id 'scala'
}
repositories {
mavenCentral()
}
dependencies {
implementation "org.scala-lang:scala-library:2.10.1"
}
def scalaClasspath = scalaRuntime.inferScalaClasspath(configurations.compileClasspath)
// The returned class path can be used to configure the 'scalaClasspath' property of tasks
// such as 'ScalaCompile' or 'ScalaDoc', or to execute these and other Scala tools directly.

Method Summary
Modifier and TypeMethodDescriptionfindScalaJar(Iterable<File> classpath, String appendix) Searches the specified class path for a Scala Jar file (scala-compiler, scala-library, scala-jdbc, etc.) with the specified appendix (compiler, library, jdbc, etc.).getScalaVersion(File scalaJar) Determines the version of a Scala Jar file (scala-compiler, scala-library, scala-jdbc, etc.).inferScalaClasspath(Iterable<File> classpath) Searches the specified class path for a 'scala-library' Jar, and returns a class path containing a corresponding (same version) 'scala-compiler' Jar and its dependencies.

inferScalaClasspath
Searches the specified class path for a 'scala-library' Jar, and returns a class path containing a corresponding (same version) 'scala-compiler' Jar and its dependencies.The returned class path may be empty, or may fail to resolve when asked for its contents.
- Parameters:
classpath- a class path containing a 'scala-library' Jar- Returns:
- a class path containing a corresponding 'scala-compiler' Jar and its dependencies
-
findScalaJar
Searches the specified class path for a Scala Jar file (scala-compiler, scala-library, scala-jdbc, etc.) with the specified appendix (compiler, library, jdbc, etc.). If no such file is found,nullis returned.- Parameters:
classpath- the class path to searchappendix- the appendix to search for- Returns:
- a Scala Jar file with the specified appendix
-
getScalaVersion
Determines the version of a Scala Jar file (scala-compiler, scala-library, scala-jdbc, etc.). If the version cannot be determined, or the file is not a Scala Jar file,nullis returned.Implementation note: The version is determined by parsing the file name, which is expected to match the pattern 'scala-[component]-[version].jar'.
- Parameters:
scalaJar- a Scala Jar file- Returns:
- the version of the Scala Jar file
