title: How to configure jacoco4sbt with Play Framework 2.3
body: <p>I decided to use jacoco4sbt as our Java code coverage tool for our Play 2.3 project. I followed the instructions from <a href="https://github.com/sbt/jacoco4sbt/wiki" rel="nofollow">jacoco4sbt</a> but for some reason some of the tests fail when I execute <code>activator jacoco:coverage</code> and no coverage report gets generated. All unit tests pass when I run <code>activator test</code>. In my build.sbt file I have  </p>
  
  <p><code>jacoco.settings 
   parallelExecution in jacoco.Config := false
   libraryDependencies ++= Seq(
      javaJdbc,
      javaEbean,
      cache,
      javaWs,
      "com.google.inject" % "guice" % "3.0",
      "com.github.fge" % "json-schema-validator" % "2.1.7",
      "org.openl" % "org.openl.core" % "5.13.2",
      "org.openl.rules" % "org.openl.rules" % "5.13.2")</code>   </p>
  
  <p>However, when I run jacoco:parallelExecution it still says true. In my plugins.sbt file I have added <code>addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.6")</code> </p>
  
  <p>When I'm in activator and I run <code>jacoco:report</code> I get the following error <code>(jacoco:report) java.io.FileNotFoundException: C:\users\me\project\target\scala-2.11\jacoco\jacoco.exec (The system cannot find the file specified)</code></p>
  
  <p>When I run an about I get </p>
  
  <pre><code>[info] This is sbt 0.13.5

  <p>Do I need to have a specific jacoco config file, and if so where?
  I notice that executing <code>jacoco:test</code> runs the tests successfully. Afterwards when I run <code>jacoco:report</code>, I get that same file not found error I mentioned. </p>
