When trying to use this in a ruby-verticle like so:

require 'vertx'

psql_config = {
  address: "db-psql",
  connection: "PostgreSQL",
  maxPoolSize: 5,
  username: "recipebook",
  password: "$uper$ecret",
  database: "recipebooks",
}

Vertx.deploy_module("io.vertx~mod-mysql-postgresql~0.2.0", psql_config)
Vertx.deploy_verticle("server.rb", {}, 4)

where server.rb looks like:

require 'vertx'
require 'pp'

include Vertx

rm = RouteMatcher.new

rm.get('/recipes') do |req|
  EventBus.send("db-psql", { action: :select, table: :recipes }.to_json) do |reply|
    Vertx.logger.info reply.pretty_inspect
    req.response.end(reply.body.to_json)
  end
end

rm.get('/recipes/:id') do |req|
  req.response.status_code(404).end({ error: 'no such book'}.to_json);
end

HttpServer.new.request_handler(rm).listen(8080)

it throws this error:

What is wrong?

Not sure about that yet. Are you using Scala 1.0.0-RC1 in your langs.properties? Can you try with 0.3.0? Maybe that's still an issue. I'm trying to update to Scala 1.0.0-RC1 but have trouble with the new VertxExecutionContext. Hopefully this will be resolved soon.

Same thing, different output...

Perhaps mixing and matching this with Ruby is not the best of ideas 😏...

Just to be sure: You've tried Scala lang 0.3.0 and the master branch of this module (0.3.0-SNAPSHOT)?

😱 it works now!

Thx for the help; perhaps these learned lessons need a place in the readme? 😉

What is the ETA for this to update to scala lang 1.0.x?

@coffeeaddict do you have to change your module to scala lang 0.3.0 or just postgres mod's scala lang to 0.3.0?
