IntelliJ Scala cannot build a simple project (SBT can)

Question

I installed IntelliJ idea community edition 14.1.3 on my windows 7 machine.

I created a simple sbt project where the build.sbt file looks like

name := "SlickTest"

version := "1.0"

scalaVersion := "2.11.6"

libraryDependencies ++= Seq(
  "com.typesafe.slick" %% "slick" % "3.0.0-RC3",
  "org.slf4j" % "slf4j-nop" % "1.6.4",
  "com.typesafe" % "config" % "1.0.2"

)

Now I wrote a simple class

import com.typesafe.config.ConfigFactory

object Foo {
  def main(args : Array[String]): Unit = {
    println("foo")
    val conf = ConfigFactory.load()
    val foo = conf.getString("derby.url")
    println(foo)
  }
}

I created a file called "application.conf" in the resources folder.

derby = {
  url = "foo"
}

Now if I go to command line and say sbt clean compile run I can see

D:\myapps\Scala\SlickTest>sbt clean compile run

D:\myapps\Scala\SlickTest>

but when I try to build the same project in Intellij idea I see

Does anyone know why can't IntelliJ build the same project when sbt can easily build it.

I searched for couple of could not find output directory threads but they did not help me because unlike others I don't have a capitalization error in my path or project name.

Answer 1

Open Project settings and fill up the input with output path for this project, as on the image below.
