I have a gradle task written in Groovy
task packageFatJar(type: Jar) {
    group 'build'
    description 'package fat jar for migrations app with all dependencies'
    baseName = 'app-fat'
    zip64 = true
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    with jar
}
I want to change it to Groovy DSL
I have this code ready:
tasks.create<Jar>("packageFatJar") {
    group = "build"
    description = "package fat jar for group call common app with all dependencies"
    baseName = "app-fat"
    isZip64 = true
}
But, I don't know how to convert this part:
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
with jar
Can you please help me?
