I'm using the Groovy plug-in, and run the following snippet as system:

import hudson.model.*
def version = build.buildVariableResolver.resolve("VERSION")
println "VERSION=$version"
def nextJobName = 'MY_NEXT_JOB'
def nextJob = Hudson.instance.getItem(nextJobName)
def running = nextJob.lastBuild.building
if (running) {
   println "${nextJobName} is already running. Not launching"
} else {
   println "${nextJobName} is not running. Launching..."
   def params = [
      new StringParameterValue('VERSION', version)
   ]
   nextJob.scheduleBuild2(0, new Cause.UpstreamCause(build), new ParametersAction(params))
}

It works like a charm.
