build.gradle looks like:

buildscript {
    repositories {
        mavenLocal()
    }
    dependencies {
        classpath group: 'org.gradlefx', name: 'gradlefx', version: '0.5'
    }
}

apply plugin: 'gradlefx'
type = 'swc'

I'm getting the following stack trace

$ gradle build

It looks to me like I'm not declaring a type, but as you can see, I am. Any ideas or suggestions?
