https://kotlinlang.org/docs/reference/using-maven.html says:

If you're targeting JDK 7 or JDK 8, you can use extended versions of the Kotlin standard library which contain additional extension functions for APIs added in new JDK versions. Instead of kotlin-stdlib, use kotlin-stdlib-jdk7 or kotlin-stdlib-jdk8, depending on your JDK version (for Kotlin 1.1.x, kotlin-stdlib-jre7 and kotlin-stdlib-jre8).
