Thanks, that's great news. We can't use a manually downloaded Jar file, but will update once a new proguard-gradle is available from Maven Central. (Would be great to have beta1 published there.)

This has become a blocker for us, as the previously mentioned workaround jvmTarget=1.6 no longer works on JDK 9.

Any updates on this?

I'm running into the same problem. Only workaround I could find is to compile Kotlin with jvmTarget=1.6, but that's not a long-term solution.
