title: mvn package fails with new SpringBoot project
body: <p>I just downloaded the default SpringBoot project with default settings from the <a href="https://start.spring.io/" rel="nofollow noreferrer">initilizizer</a>:</p>
  
  <p>Here's my codebase after several test codes:<br>
  I had no problem with rest api, thymeleaf but I failed with JPA.</p>
  
  <p>Build fails:</p>
  
  <pre><code>package javax.persistance does not exist
  cannot find symbol [ERROR]   symbol: class Entity
  </code></pre>
  
  <p>It failed just after adding entity annotation, nothing else:   </p>
  
  <p>I really like Java. <strong>I can't tell you how I want to learn this language</strong>...and I believe that I can be successful with the syntax, I can understand the tutorials. This is my only serious problem before moving forward. </p>
