org.gradle.api.tasks.ScalaRuntime

@Incubating
public class ScalaRuntime
extends Object

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:

     apply plugin: "scala"

     repositories {
         mavenCentral()
     }

     dependencies {
         compile "org.scala-lang:scala-library:2.10.1"
     }

     def scalaClasspath = scalaRuntime.inferScalaClasspath(configurations.compile)
     // 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.

メソッドの詳細

inferScalaClasspath

public FileCollection 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.

If the (deprecated) 'scalaTools' configuration is explicitly configured, no repository is declared for the project, no 'scala-library' Jar is found on the specified class path, or its version cannot be determined, a class path with the contents of the 'scalaTools' configuration is returned.

The returned class path may be empty, or may fail to resolve when asked for its contents.

パラメータ:

classpath - a class path containing a 'scala-library' Jar

戻り値:

a class path containing a corresponding 'scala-compiler' Jar and its dependencies

findScalaJar

@Nullable
public File findScalaJar(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.). If no such file is found, null is returned.

パラメータ:

classpath - the class path to search

appendix - the appendix to search for

戻り値:

a Scala Jar file with the specified appendix

getScalaVersion

@Nullable
public String getScalaVersion(File scalaJar)

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, null is returned.

Implementation note: The version is determined by parsing the file name, which is expected to match the pattern 'scala-[component]-[version].jar'.

パラメータ:

scalaJar - a Scala Jar file

戻り値:

the version of the Scala Jar file
