java.lang.NoClassDefFoundError when running Scala JUnit Test on Scala IDE (Eclipse Kepler)

I've recently decided to install Scala IDE 3.0.3 (which is basicly Eclipse Kepler with scala plugin). I've newest specs (specs2_2.10-23.11), scalaz (2.10-7.0.4), collection (scalaj-collection_2.10-1.5) and scala library [2.10.4]

I tried to run my tests in scala using "Scala JUnit Test" but i got this error

java.lang.NoClassDefFoundError: scalaz/concurrent/Strategy$ at org.specs2.reporter.DefaultExecutionStrategy$$anonfun$execute$1$$anonfun$2.apply(ExecutionStrategy.scala:43) at org.specs2.reporter.DefaultExecutionStrategy$$anonfun$execute$1$$anonfun$2.apply(ExecutionStrategy.scala:41) at scala.collection.LinearSeqOptimized$class.foldLeft(LinearSeqOptimized.scala:111) at scala.collection.immutable.List.foldLeft(List.scala:84) at org.specs2.reporter.DefaultExecutionStrategy$$anonfun$execute$1.apply(ExecutionStrategy.scala:41) at org.specs2.reporter.DefaultExecutionStrategy$$anonfun$execute$1.apply(ExecutionStrategy.scala:38) at scalaz.syntax.IdOps$class.$bar$greater(IdOps.scala:15) at scalaz.syntax.ToIdOps$$anon$1.$bar$greater(IdOps.scala:78) at org.specs2.reporter.JUnitReporter$class.report(JUnitReporter.scala:44) at org.specs2.runner.JUnitRunner$$anon$4.report(JUnitRunner.scala:43) at org.specs2.runner.JUnitRunner.run(JUnitRunner.scala:50) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

Caused by: java.lang.ClassNotFoundException: scalaz.concurrent.Strategy$ at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 17 more

What causing that? I probably missing something but I can't find what.

My tests are running just fine with gradle.

Well meaby someone will find it helpfull. I find solution: I missed scalaz-concurrent jar which apparently is not included in scalaz-core. Note that you need the same version of core and concurrent in order to work.
