Also, even worse, what about different kotlin versions also?

From: https://docs.gradle.org/current/userguide/dependency_resolution.html#sec:version-conflict

Highest version are chosen.
Note plugin version and dependency version is mutually exclusive hence its why you don’t exactly need to declare the stdlib dependency version and just let the Kotlin plugin does it for you.

As for jdk7 and jdk8 libraries, they expose extension methods for Java classes that is introduced in jdk7 (try with resources which supported by Kotlin use extensions on AutoCloseable (Java 7+ only) or jdk8 (Streams, Java 8+ only).

In pure Kotlin project, you need neither. You at least want jdk7 lib though if you do any IO with Java interop.

right, but dont jdk8 and jdk7 overlap? i.e. could cause runtime issues if both are on classpath?

No, they are complementary.
