Starting Scala REPLs with Gradle and SBT

2015-07-04 Discuss

These examples are tailored for usage with the Atomic Scala exercises, but they demonstrate the principles.

build.gradle ```groovy apply plugin: 'scala'

repositories { mavenCentral() }

ext { versions = [ commons_math3: '3.5', jline: '2.12.1', scala: '2.11.6' ] }

dependencies { compile "org.apache.commons:commons-math3:${versions.commons_math3}" compile "org.scala-lang:scala-library:${versions.scala}"

runtime "jline:jline:${versions.jline}"
runtime "org.scala-lang:scala-compiler:${versions.scala}"

}

sourceSets { main { scala { srcDirs = ['.'] include 'AtomicTest.scala' } } }

scalaConsole.dependsOn(build) scalaConsole.classpath += sourceSets.main.runtimeClasspath

// usage: gradlew scalaConsole -q ```

build.sbt ```scala scalaVersion := "2.11.6"

sources in Compile <<= (sources in Compile).map( filter(.name == "AtomicTest.scala"))

libraryDependencies += "org.apache.commons" % "commons-math3" % "3.5"

initialCommands in console := """ |import org.apache.commons.math3. |import com.atomicscala.AtomicTest. |""".stripMargin

// usage: sbt console ```
