Grails JAR dependencies with classifiers

Quick post on specifying Grails dependencies in BuildConfig.groovy.  The recommended way to suck in JAR dependencies in Grails is to use the dependencies DSL maintained in BuildConfig.groovy.  I had a need to bring down a dependency that has a classifier attribute on it.  Didn't really find anything definitive on how to do it, but it seemed like following a convention might do the trick.  Here's how I solved the issue:

repositories {

  grailsPlugins()

  grailsHome()

  grailsCentral()

  mavenCentral()

  ebr() // SpringSource Enterprise Bundle Repository

}

dependencies {

  runtime group:'net.sf.json-lib', name:'json-lib', version:'2.4', classifier:'jdk15'

}
