Answer 1

You can specify compiler args inside kotlinOptions closure on tasks of KotlinCompile type. For all of them, for instance:

allprojects {
    ...

    tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
        kotlinOptions {
            jvmTarget = '1.6'
            freeCompilerArgs += '-include-runtime'
        }
    }
}

If anyone is using the kotlin DSL you can try this too:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

val compileKotlin: KotlinCompile by tasks
compileKotlin.kotlinOptions.includeRuntime = true

Answer 3

Try this:

compileKotlin {
    kotlinOptions.includeRuntime = true
}

UPD btw this exact option includeRuntime couldn't work because it is not Gradle way. There are many options to build jar with dependencies in Gradle: Gradle – Create a Jar file with dependencies, Gradle Shadow
