what's the Kotlin counterpart of something like this?

jar {
    from {
        (configurations.compileClasspath - configurations.exclusion).collect {
            it.isDirectory() ? [] : zipTree(it).matching {
                include "lib/**",..
            }
        }
    }
}

from(provider {
    (configurations.compileClasspath.get() - configurations.exclusion.get()).map { … }
})

?
