Application is very simple, e.g.:
package com.rainysoft.decisiontree.application
import com.rainysoft.decisiontree.tree._
object Application extends App {
println("Hello World")
}
Build file is:
apply plugin: 'scala'
repositories {
mavenCentral()
}
dependencies {
compile 'org.scala-lang:scala-library:2.11.2'
testCompile 'org.scala-lang:scala-library:2.11.2'
}
compileScala {
scalaCompileOptions.useCompileDaemon = true
}
Gradle version is 2.0 (latest available as of writing, just downloaded). OS is Mac but I had the same issue on Windows.
Without scalaCompileOptions.useCompileDaemon there is no problem. With it, as stated under 25.8: http://www.gradle.org/docs/current/userguide/scala_plugin.html, there is an “internal compiler error” without much details.
