    i guess i've worked this into a more general question: what do i need to write in kotlin to get the output to be a static method?

    I am trying to install Kotlin onn my ubuntu 16.04 using the instructions here https://www.cyberciti.biz/faq/how-to-install-kotlin-programming-language-on-ubuntudebian-linux/ I get the following: Stop! The archive was corrupt and has been removed! Please try installing again. Any suggestions 12 replies sdkman downloads kotlin binary from github and today there was github service outage, so the archive might be downloaded incompletely.

    i could just create a java class that wraps this code

    this should work
  • l

    liamd

    07/31/2017, 6:39 PM
    it seems to me i should either be able to use a top-level main declaration
  • l

    liamd

    07/31/2017, 6:40 PM
    then pass the "...Kt" class
  • k

    karelpeeters

    07/31/2017, 6:40 PM
    Unfortunately I'm not familiar with spark, but a top level main in a file should result in a static main in 
    ...Kt
    indeed.
