title: Cannot add task ':jacocoTestReport' as a task with that name already exists
body: <p>I am trying to add the following task so that I can get some coverage data in my java + kotlin project (for what it is worth, this is a gradle project)... but I get the following error : </p>
  
  <p>"Cannot add task ':jacocoTestReport' as a task with that name already exists"</p>
  
  <p>Here is the actual task I am trying to add : </p>
  
  <pre><code>task jacocoTestReport(type: JacocoReport, dependsOn: "testDebugUnitTest") {
  group = "Reporting"
  description = "Generate Jacoco coverage reports for Debug build"
  
  reports {
      xml.enabled = true
      html.enabled = true
  }
  
  // what to exclude from coverage report
  // UI, "noise", generated classes, platform classes, etc.
  def excludes = [
          '**/R.class',
          '**/R$*.class',
          '**/*$ViewInjector*.*',
          '**/BuildConfig.*',
          '**/Manifest*.*',
          '**/*Test*.*',
          'android/**/*.*',
          '**/*Fragment.*',
          '**/*Activity.*'
  ]
  // generated classes
  classDirectories = fileTree(
          dir: "$buildDir/intermediates/classes/debug",
          excludes: excludes
  ) + fileTree(
          dir: "$buildDir/tmp/kotlin-classes/debug",
          excludes: excludes
  )
  
  // sources
  sourceDirectories = files([
          android.sourceSets.main.java.srcDirs,
          "src/main/kotlin"
  ])
      executionData = files("$buildDir/jacoco/testDebugUnitTest.exec")
  }
  </code></pre>
  
  <p>Now, the issue I am confused about here, is that I can't find another class of this name anywhere... so perhaps there is something funky going on? I have tried googling this, but haven't really been able to find anything which truly helps me solve the problem.</p>
  
  <p>All help greatly appreciated. I realize this is not a java or kotlin specific problem - but since it is a joint java + kotlin project, I thought I would tag both in this question, in case there is some nuanced issue that somebody else has seen.</p>
