Exception Occurs when Running Scala Test from Eclipse

I downloaded the Scala IDE Linux - 64 bit For Scala 2.11.2 and am trying to run a Scala Test. Following is my code.

package ppg.experiment.gameofbusiness.engine

import org.scalatest.FlatSpec
import org.scalatest.Matchers

class DiceSpec extends FlatSpec with Matchers {

  "A dice" should "roll a value greater than zero" in {
    new Dice().roll > 0
  }
  it should "roll a value less than six" in {
    new Dice().roll < 7
  }
}

When I right click and run as Scala Test the following is printed on the console

WARNING: -p has been deprecated and will be reused for a different (but still very cool) purpose in ScalaTest 2.0. Please change all uses of -p to -R.

Can someone tell me how to solve this problem?

Solution

  • Check your classpath; in particular check that the version of scalatest you're depending on is compiled for scala 2.11, not 2.10.
