How to attach sources to scala sbt project at Intellij Idea?

Question

I am new at scala. And for start I want to use Intellij 13.1.5 IDE.

However IDE can't attach sources. Here is how it looks for AnyVal:

Search at internet can't find any source.

I tried Attach sources and attach unpacked scala archive. It doesn't work either.

UPDATE:

Here is sbt configuration:

name := "scalatest-selenium"

version := "1.0"

scalaVersion := "2.11.1"

libraryDependencies ++= Seq(
  "net.sourceforge.htmlunit" % "htmlunit" % "2.14",
  "org.seleniumhq.selenium" % "selenium-java" % "2.42.2",
  "org.scalacheck" % "scalacheck_2.10" % "1.11.4" % "test",
  "org.scalatest" % "scalatest_2.11" % "2.2.0" % "test"
)

testOptions in Test += Tests.Argument(TestFrameworks.ScalaTest, "-u", "target/test-reports")

How to solve this trouble?

Answer 1

I get rid of this trouble at the following way:

removed the .sbt directory in your Home Folder.

When you run sbt again, the new folder is created in the correct format and the error goes away.
