title: kotlin fun main(args : Array<String>) doesn't work in command line
body: <p>In Kotlin 1.3.30 I just installed, the main entry function doesn't work in command line. JDK is version 8. Intellij Idea is 2019.1.1. No dependency, very clean project.</p>
  
  <p>When I started learning Kotlin, the main entry is 'fun main(args: Array)'. Last year, 'fun main()' could be used without 'args' and I used it a lot.
  Now I have a project needs command line parameters, but something goes wrong. I've tried 3 formats:</p>
  
  <pre><code>// 1. doesn't work.
  fun main(vararg args: String){
      println("this is a test.")
  }
  
  // 2. doesn't work
  fun main(args: Array&lt;String&gt;){
      println("this is a test.")
  }
  
  // 3. this works. but where can I get the command line parameters?
  fun main(){
      println("this is a test.")
  }
  </code></pre>
  
  <p>1 &amp; 2 has same response:</p>
  
  <pre><code>λ java -jar test-1.0-SNAPSHOT.jar

  <p>It works fine with 3 without changing any other thing. But I need command line args.</p>
