How to exclude library from all dependencies in Kotlin DSL build.gradle?

This works with the Gradle Kotlin DSL:

configurations {
    all {
        exclude(group = "com.google.guava", module = "listenablefuture")
    }
}

This might work (though I haven't tried it):

configurations.forEach { it.exclude("com.google.guava", "listenablefuture") }
