Update: July 26, 2019
This section of the forum is now closed; we are working on a new support model for WDL that we will share here shortly. For Cromwell-specific issues, see the Cromwell docs and post questions on Github.

Is the 'version #' statement supported by Cromwell 42?

I tried using the version statement as the first line of my WDL script but Cromwell 42 does not accept it. It parses the WDL file as draft-2 even if I specify --type-version as an input to Cromwell.

=> cat helloworld.wdl 
version draft-3
workflow helloworld {
String greeting

call hello { input: greeting=greeting }

meta {
      author : "Walt Shands"
      email : "[email protected]"
      description: "This is a hello world example"
   }
}

task hello {
    String greeting
  command {
    echo "${greeting}"
  }
}

=> cat helloworld.json 
{
  "helloworld.greeting": "hi everyone!"
}

How do I specify the version of the WDL file?
