title: Jacoco Gradle jacocoTestReport task failing Error while generating report - Is a directory
body: <p>I'm using Gradle 1.6.</p>
  
  <p>I run the following command and it works fine for all projects<br/>
  <strong>gradle clean build jacocoTestReport</strong> </p>
  
  <p>Today, I'm seeing that one of the project is failing during "jacocoTestReport" section. PS attached error log.</p>
  
  <p><strong>The main error lines are</strong>: <br/><br/>
  12:35:45.920 [ERROR] [org.gradle.BuildExceptionReporter] Caused by: : Error while creating report <br/>....<br/>
  12:35:45.924 [ERROR] [org.gradle.BuildExceptionReporter] Caused by: java.io.FileNotFoundException: /production/jenkinsAKS/workspace/MFUSvc/src/java-test/com/thc/ids/ws/mfu/msg/formulary (Is a directory) <br/></p>
  
  <p><strong>Few points to note:</strong><br/></p>
  
  <ol>
  <li>This project was building finee without an error but today I'm
  seeing this error. </li>
  <li><p>I tried using two/different versions of jacoco (as shown below) - jacocoTestReport task works fine in all other projects using both versions, but fails for this one.</p>
  
  <p><em>jacoco {<br/>
    //toolVersion = "0.6.2.201302030002"<br/>
    toolVersion = "0.7.0.201403182114"<br/>
    // reportsDir = file("$buildDir/customJacocoReportDir")<br/>
  }<br/></em></p></li>
  <li><p>Under the given src/java-test/.../... path, I see a valid .java file and in my workspace (once compileJava etc Gradle tasks are complete, I see build/classes/{main, test, integrationTest}/... folders contains a valid .class file (for that path which is showing up in the error and saying "Is a directory".</p></li>
  </ol>
  
  <p>Any idea what I'm missing.</p>
