Compiler problem with Scala and hawtdispatch-scala-1.12.jar

[Oliver Plow]

Hello,

I have trouble getting this code here to compile:

import org.fusesource.hawtdispatch._

trait AsyncUtils {
  def async(task: => Unit) {
    getGlobalQueue(HIGH).execute(task)
  }
}

The error message is:

scala: bad symbolic reference. A signature in package.class refers to type DispatchQueue
in package org.fusesource.hawtdispatch which is not available.
It may be completely missing from the current classpath, or the version on
the classpath might be incompatible with the version used when compiling package.class.

Same for this code:

import org.fusesource.hawtdispatch._
trait AsyncUtils {
  def async(task: => Unit) {
    val queue = createQueue("session")
    queue{ task() }
  }
}

Then this code:

trait AsyncUtils {
  def async(task: => Unit) {
    getGlobalQueue(HIGH).execute{ task() }
  }
}

creates the compiler error "scala: not found: value HIGH".

because of "or the version on the classpath might be incompatible with the version used when compiling package.class." I also tried with Scala 2.9.3 and Scala 2.10. The errors occur when using IDEA and also the Scala eclipse plugin. I'm at my wits' end ...

Thanks, Oliver

You also need the hawtdispatch-1.12.jar on the classpath.

Thanks, that did it :-). Looks now like this and runs also fine:

import org.fusesource.hawtdispatch._

trait AsyncUtils {
  def async(task: => Unit) {

    getGlobalQueue(HIGH) { task }
