IncompatibleClassChangeError : Found class scala.collection.mutable.ArrayOps, but interface was expected

[Anuj Mehta]

I had created a simple scala project. Using sbt-assembly I had created a jar that includes class files of both src and test classes.

Now I had placed the jar generated in a new folder and I trying to execute the suite when I encounter this error

Scala version: 2.10.2
ScalaTest Version: 2.10

Dependency declared in build.sbt

libraryDependencies += "org.scalatest" % "scalatest_2.10" % "2.0" % "test"

I am getting following exception

E:\Workspace\test_1>scala -cp Solution-test-0.1.jar org.scalatest.tools.Runner -s test.scala.SolutionSuite

java.lang.IncompatibleClassChangeError: Found class scala.collection.mutable.ArrayOps, but interface was expected

I am attaching my test suite file for reference. Please guide

Hi Anuj,

That sounds like a mismatch between Scala versions. Could part of the class files in your jar be compiled with Scala 2.9 and part with Scala 2.10?
