Basic Gradle build file for a project using GroovyFX 0.2

build.gradle

apply plugin:'groovy'

project.ext.set('javafxHome', System.env['JAVAFX_HOME']

repositories { mavenCentral() }

dependencies {
    groovy 'org.codehaus.groovy:groovy-all:1.8.6'
    compile 'org.codehaus.groovyfx:groovyfx:0.4.0'
    compile files("${javafxHome}/rt/lib/jfxrt.jar")
}

task run(type: JavaExec) {
    main = 'helloGroovyFX'
    classpath sourceSets.main.runtimeClasspath
}

task makeDirs(description:'make all dirs for project setup') << {
    def sources = [sourceSets.main, sourceSets.test]
    sources*.allSource*.srcDirs.flatten().each { File srcDir ->
        println "making $srcDir"
        srcDir.mkdirs()
    } 
}

task wrap(type:Wrapper, description:"create a gradlew") {
    gradleVersion = '1.0-rc-3'
}

newer versions of gradle (since 1.0-milestone-9) prefer the syntax project.ext.set('javafxHome', System.env['JAVAFX_HOME']) instead of setting a dynamic property (line 3).

if javafx lib is already on the path you don't need javafxHome, as the version groovyfx:8.0.0 this is working for me:

apply plugin: 'groovy'
repositories {
    jcenter()
}
dependencies {
    compile 'org.groovyfx:groovyfx:8.0.0'
}
task run(type: JavaExec) {
    main = 'helloGroovyFX'
    classpath sourceSets.main.runtimeClasspath
}
