Does anyone have an example of a real world multi-file Kotlin based gradle build? Especially with using plugins in the non-`build.gradle.kts` files? I'm a complete newbie to the Kotlin DSL and struggling with getting plugins to work in a `foo.gradle.kts` file, and it would be nice to see how others have done it.

What do you mean “multi-file Kotlin based gradle build”?
Do you mean with `apply(from="foo.gradle.kts")`?

It’s not the best way to share logic with Kotlin DSL, use buildSrc instead

there is a bunch of good examples on kotlin-dsl github
<https://github.com/gradle/kotlin-dsl/tree/master/samples>

also see this part of migration guide:
<https://guides.gradle.org/migrating-build-logic-from-groovy-to-kotlin/#migration_strategies>

But you still can use script plugins (include gradle files) if you want, it can be helpful if you migrate from groovy to kotlin, if you need this, check samples on kotlin-dsl repo

Yeah, it was using `apply(from="foo.gradle.kts")`. I've got a lot of tasks, more so than actual logic, so I thought it was more reasonable for them to be in `.gradle.kts` file(s). The samples repo shows using multiple `.kts` files, but doesn't show anything about using plugins in those included files, and that's where I'm hitting unresolved symbol errors

yes, plugins application doesn’t work for now in script plugins

Use buildSrc for such tasks instead (add plugins as dependencies to buildSrc), you can find examples of this approach on kotlin-dsl github

Ah, right. What I want to do is something like this project: <https://github.com/gradle/kotlin-dsl/tree/master/samples/modularity> but be able to create tasks from plugins. So do you mean this isn't supported right now?

This is supported, but not with `plugins{}` dsl, so you cannot use any type safe API of Kotlin DSL.
There are some other ways, use buildscript or add plugins as dependencies to buildSrc (will be available in script plugins too)

See
<https://github.com/gradle/kotlin-dsl/issues/427>

OK, I think I've got it. I'll look to see how I can restructure things to use `buildSrc` and whatnot. Thanks for the help!

Please ask if you have additional questions about this :+1:
And check migration guide, it’s very helpful document
