Vert.x - java.lang.IllegalStateException: No language implementation known for prefix D

Question

I am writing the Eclipse plug-in for Vert.x. When hello-vorld.js is launched with a command line like:

D:\Progs\vertx\vert.x-2.1M5\bin\vertx.bat run D:\Workspaces\runtime-EclipseApplication\Vertx2\hello-vorld.js

I get the same error twice:

hello-vorld.js contains

var vertx = require('vertx');

vertx.createHttpServer().requestHandler(function(req) {
  req.response.end("Hello World!");
}).listen(8080, 'localhost');

Answer 1

Vert.x takes D: as a language runtime qualifier.

Use:

D:\Progs\vertx\vert.x-2.1M5\bin\vertx.bat run rhino:D:/Workspaces/runtime-EclipseApplication/Vertx2\hello-vorld.js
