Gradle / Grails application - grails

Question

I have been trying to configure Gradle to manage a Grails project for a couple of hours with no success. The suggestions I've found here on Stack Overflow and elsewhere on the Internet didn't work for me.
Could you please give me up-to-date directions on how to configure a Gradle+Grails project? Ideally it should relate to the current versions of Grails (2.1.0) and Gradle (1.1).

BuildScript
import org.grails.gradle.plugin.GrailsTask
buildscript {
repositories {
mavenCentral()
mavenRepo name: "grails", url: 'http://repo.grails.org/grails/repo'
}
dependencies {
classpath "org.grails:grails-gradle-plugin:1.1.1-SNAPSHOT"
}
}
repositories {
mavenCentral()
mavenRepo name: "grails", url: 'http://repo.grails.org/grails/repo'
}
version = "1.0"
grailsVersion = "2.1.0"
apply plugin: "grails"
dependencies {
['dependencies', 'resources', 'core', 'hibernate', 'plugin-datasource', 'plugin-domain-class', 'plugin-tomcat', 'plugin-services'].each { plugin ->
compile "org.grails:grails-$plugin:2.1.0"
}
bootstrap "org.codehaus.groovy:groovy-all:1.8.6"
}
GRAILS_TASK_PREFIX = "grails-"
if (name.startsWith(GRAILS_TASK_PREFIX)) {
project.task(name, type: GrailsTask) {
command "${name - GRAILS_TASK_PREFIX}"
}
}
Initialize
Then you can do gradle init to initialize the project structure
Commands
Use gradle grails-[grails script] to execute your grails commands. For example: gradle grails-run-app is equivalent to grails run-app
Hope this helps!
Update
This seems to work for Grails 2.3.2:
buildscript {
repositories {
mavenCentral()
maven { url 'http://repo.grails.org/grails/repo' }
}
dependencies {
classpath "org.grails:grails-gradle-plugin:2.0.0-SNAPSHOT"
}
}
repositories {
mavenCentral()
maven { url 'http://repo.grails.org/grails/repo' }
}
version = "1.0"
apply plugin: "grails"
apply plugin: 'idea'
grails {
grailsVersion = "2.3.2"
}
dependencies {
['dependencies', 'core', 'spring', 'web', 'plugin-datasource', 'plugin-domain-class', 'plugin-controllers', 'plugin-services'].each { plugin ->
compile "org.grails:grails-$plugin:2.3.2"
}
compile 'org.grails.plugins:tomcat:7.0.42'
compile 'org.grails.plugins:hibernate:3.6.10.3'
compile 'com.h2database:h2:1.3.173'
bootstrap "org.codehaus.groovy:groovy-all:2.1.9"
}
A note, throws Exception when generating Grails wrapper, but gradle init seems to initialize the project structure properly otherwise. And, gradle grails-run-app seems to work fine too.
