Java.io.File.forEachLine not working?

1

I get compile error with the following code for reading file?

``

package test

fun main(args : Array<String>) {

     val file = java.io.File(args[0])

     file.forEachLine{ line -> println(line) }

}

output>

It's a bug in the standard library, a wrokaround would be: 

package test
fun main(args : Array<String>) {
    val file = java.io.File(args[0])
    file.forEachLine("UTF-8") { line -> println(line) }
}

The problem will be fixed in the next nightly build. Thanks for the report.

I've created a ticket to track this: http://youtrack.jetbrains.com/issue/KT-3101

Zemian, This should be already fixed -- please upgrade to the latest nightly build (http://teamcity.jetbrains.com)

Yes, I can verified that it's fixed in 0.4.249 now. Thanks Andrey.
