Hi.&nbsp;&nbsp;

I thought I followed Hadi’s blog

[http://hadihariri.com/2012/02/17/the-kotlin-journey-part-i-getting-things-set-up/](http://hadihariri.com/2012/02/17/the-kotlin-journey-part-i-getting-things-set-up/)

to the letter in getting helloworld to run, but I’m having problems.&nbsp;&nbsp;No matter what I do, I cannot seem to find the menu entry that shows “Run namespace” so I can run the app.

Here is my Kotlin file:

import java.util.ArrayList

fun main(args : ArrayList\<String\>) : Unit {  
&nbsp;&nbsp;print(“hello ${args[0]}”)  
}

Attached is a screenshot showing my options when I bring up the menu in the editor.

I’m using EAP 114.145 11.1 and plugin version kotlin-plugin-0.1.1358.zip.

Can someone suggest what I may be doing wrong?&nbsp;&nbsp;I’ve spent an hour trying to figure this out, but to no avail.

Thank you kindly.

Try to declare some package at the beginning of source file, maybe it helps.

I tried this:

package foo

import java.util.ArrayList

fun main(args : ArrayList\<String\>) : Unit {  
&nbsp;&nbsp;print(“hello ${args[0]}”)  
}

but it still produces no “Run namespace” in the popup.

Hi!

Try using Array\<String\> instead of ArrayList\<String\>. 🙂

Incidentally, for those of you reading along now or later, to run this code from the command line, do

$&nbsp;&nbsp;java -cp lib/kotlin-runtime.jar:out/production/kotlin-lab foo.namespace
