Questions:
1. Why am I getting this error?
2. Is there a specific relationship between `version()` and `bundle()` aliases, or are they separate? I would expect that the aliased libraries can all have different version values and that a bundle isn't restricted to having only a single version value per bundle.

odd error.  `listOf`should be resolve to stdlib - perhaps check the imports.  A bundle, by definition, uses a single version applied to each entry in the bundle.  that version can be different than versions used elsewhere.

hopefully that code is indeed Kotlin and not Groovy :wink:

apologies, my statement was incorrect (mind stuck on previous BOM / catalog discussion).  A bundle is simply a grouping of dependencies, using their versions as specified.

Thanks for #2, and I think I just face palmed number 1.

no worries, it all gets blurry sometimes…

Yep. It was a duh thing. I renamed every other script in the project to `.kts`... except `settings.gradle`.
