title: Import org.apache.net.* in Kotlin
body: <p>I'm new to Kotlin and I'm trying to upload some files to my FTP server using Kotlin.</p>
  
  <p>I compile my programs on the command line as:
  <code>kotlinc main.kt -include-runtime -d main.jar</code></p>
  
  <p>And when I import <code>org.apache.commons.net.ftp.FTPClient</code> I got an error as:</p>
  
  <p><code>main.kt:7:12: error: unresolved reference: apache</code>.</p>
  
  <p>I've downloaded <code>commons-net-3.6.jar</code> but I have no ideas on how to include this file to my actual project.</p>
  
  <p>How can I do to successfully import <code>org.apache.*</code> libraries ?</p>
