body: <pre><code>task scalaTest(dependsOn: testClasses) &lt;&lt; {
      description = 'Runs Scalatest suite'
      ant.taskdef(name: 'scalatest',
              classname: 'org.scalatest.tools.ScalaTestAntTask',
              classpath: sourceSets.test.runtimeClasspath.asPath

      ant.scalatest(runpath: sourceSets.test.output.classesDir,

          reporter(type: 'stdout')
      }
  }
  </code></pre>
  
  <p>I run <code>gradle scalaTest</code> and I get:</p>
  
  <pre><code>* What went wrong:
  Execution failed for task ':scalaTest'.
  &gt; java.lang.NoClassDefFoundError: scala/reflect/ClassManifest$
  </code></pre>
  
  <p>I am using Scala 2.10.2 and Gradle 1.7</p>
  
  <pre><code>dependencies {
      compile 'org.scala-lang:scala-library:2.10.2'   
      testCompile 'org.scalatest:scalatest:1.3'
      testCompile 'org.scalamock:scalamock_2.10:3.0.1'
