title: Trying Gradle build - "Task 'build' not found in root project"
body: <p>I just started to read "Pro Spring MVC with web flow" and it comes with a code sample that I want to follow. </p>
  
  <ul>
  <li><strong>What I want</strong> - I want to build the applications as it's done in the book, using <code>Gradle</code></li>
  <li><strong>What is the problem</strong> - I have never used <code>Gradle</code> before and when I try to execute what I'm thinking I have to I get this error <code>Task 'build' not found in root project</code></li>
  <li><strong>What have I done so far</strong> - Yesterday I downloaded <code>Gradle</code> from the official site and get it to work. Today when I actually tried to execute the steps from the book it turns out that the sample code comes with its own Gradle distribution and I executed it which I think followed to getting a second distribution of Gradle. However, I don't know if this may be a problem or not. now my directory with the sample code looks like this:

  </ul>
  
  <p>Then it's written that I have to execute <code>../gradlew build</code> which I execute like this and get the following:

  <ul>
  <li><strong>What have I tried</strong> - The only thing that came to my mind was to leave only the Gradle's stuff plus the <code>appendixA-bookstore</code> folder in case Gradle recognize all directories as different builds but no success.</li>
  <li><strong>What's the final result that I want to accomplish</strong> - First I want to figure out where is my mistake and how to build the sample application(s). And also it would be perfect if I actually can do this from my first <code>Gradle</code> setup which as I wrote did yesterday and what exactly should I do to use this sample code with my fresh and original Gradle setup?</li>
  </ul>
