Compilation classpath of applied script does not include classpath of enclosing script

[bamboo]

When a Kotlin build script is applied from a main Groovy build script, its compilation classpath won't include the classpath of the main script thus the following will fail to compile even when the main buildscript classpath includes kotlin-gradle-plugin:

tasks.withType<KotlinCompile> {
    kotlinOptions.noOptimize = false
}

This is intentional. A script plugin cannot include the classpath of the project it is being applied to. Script plugins must be self-contained, as they can be applied to any number of projects.

In fact, the opposite relationship will be true in the future: The project should see what the script plugin provides. This is part of the stable plugin DSL project.
