Include interferes with imports of enum instances

[reitzig]

Consider this file repro.kts:

import Repro.Foo.Bar

enum class Foo {
    Bar
}

println(Bar)

This runs and prints Bar -- all is well.
Now, add an include directive (file can be empty):

@file:Include("shared.kt")

import Repro.Foo.Bar

enum class Foo {
    Bar
}

println(Bar)

And we get an error:

OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.intellij.util.ReflectionUtil to method java.util.ResourceBundle.setParent(java.util.ResourceBundle)

        ^

Reproduces with and without content in shared.kt, and also with comment include directive.
Also reproduces with other nested constructs such as inner classes:

sealed class Foo {
    object Bar: Foo()
}

Does not reproduce with IDEA, which runs the files just fine (and created the import statement for me, in face). Therefore, I suspect a bug in kscript.

Version : v3.0.2
Kotlin : 1.4.21-release-351
Java : JRE 14.0.2+12)

Reproduces with JRE 11 as well.

Ah. The problem is the file name of the aggregate file, isn't it? kscript would either have to use the original file names, or rewrite the imports. 🤔

It indeed assumed to the included file to be in the same package. It partially rewrites the imports to show up on top of the merged script.
