title: MultiPartEntityBuilder cannot be resolved to a type
body: <p>I  used a newer class to substitute a deprecated one. The class is MultiPartEntityBuilder. When i wrote it in the code, the compiler suggested me to import the following package</p>
  
  <pre><code>import org.apache.http.entity.mime.MultipartEntityBuilder;
  </code></pre>
  
  <p>I have imported it. But the compiler cannot still find it, giving me the error on the title</p>
  
  <pre><code>MultiPartEntityBuilder cannot be resolved to a type
  </code></pre>
  
  <p>So, it sounds quite strange to me. I've already succesfully imported similar packages</p>
  
  <pre><code>    import org.apache.http.entity.mime.HttpMultipartMode;
  import org.apache.http.entity.mime.MultipartEntity;
  import org.apache.http.entity.mime.MultipartEntityBuilder;
  import org.apache.http.entity.mime.content.ContentBody;
  import org.apache.http.entity.mime.content.FileBody;
  import org.apache.http.entity.mime.content.StringBody;
  </code></pre>
  
  <p>Does it mean i have an old version which doesn't define any class named MultiPartEntityBuilder ?
  How does the compiler know that i should import that class, part of that package, if he got an old version of that package?</p>
  
  <p>Please note that </p>
  
  <pre><code>import org.apache.http.entity.mime.MultipartEntityBuilder;
  </code></pre>
  
  <p>is market as an error.</p>
