I don't know if this is the right place, but I want to contribute to Kotlin. Unfortunately I can't build the project. I have the same error as https://kotlinlang.slack.com/archives/C19FD9681/p1499360862769923, but when I use the external gradle and maven in combination with java8, my project still don't build. Can anyone help me?

tieskedh: how's your JAVA_HOME configured?

Set to jdk8
