How do I get a jar task to include a single dependency in gradle

I have a task that looks like this (this is not the main jar this module kicks out, there is another one I can't show)

task interfaceJar(type: Jar) {
    classifier = 'interface'

    from "$buildDir/classes/main/"

    include 'x/y/z/stuff.class'
}

And some dependencies like this

dependencies {
    /* lots of dependencies */
    compile 'com.esotericsoftware:kryo:3.0.3'
}

How can I include that one specific dependency in my interfaceJar task?

To include dependency jar without unpacking it first: (Note: if you use this, you may want to add a Class-Path entry to your manifest)

task interfaceJar(type: Jar) {
    classifier = 'interface'

    from "$buildDir/classes/main/"
    from configurations.compile.findAll{it.name.contains('kryo')}

    include 'x/y/z/stuff.class'
    include '*.jar'
}

Edit: to unpack your dependency jar and include the contents in your interface jar:

task interfaceJar(type: Jar) {
    classifier = 'interface'
    from("$buildDir/classes/main/"){
        include 'stuff.class'
    }

    configurations.compile.findAll{it.name.contains('kryo')}.each{
        from(it.isDirectory() ? it : zipTree(it))
    }
}
