Migrate from gradle 8 to 9

[Munken]

What problem are you trying to solve?

Automatic migration to gradle 9

Describe the situation before applying the recipe

A gradle <= 8 build.gradle[.kts] and possibly wrapper.

Describe the situation after applying the recipe

The recipe should upgrade the wrapper to 9.

The build.gradle should be migrated according to the migration guide:
https://docs.gradle.org/9.0.0/userguide/upgrading_major_version_9.html#changes_major_9

Thanks for logging the request for Gradle 9 support at all, and migration to Gradle 9 via a recipe. We're exploring both, and likely dependent on (among other things)

• Add support for Kotlin 2.x #5575

[Munken]

Migration of gradle groovy scripts should be independent of kotlin 2 support.

You're right; these recipes were added in

• Add Gradle 9.1+ migration recipes #6010

Thanks again!
