Support Kotlin

[Richie94]

What problem are you trying to solve?

I have a Spring Boot Kotlin App where i want to migrate to Jackson 3. When Running the open-rewrite with maven, i get for every class parsing errors. "Unexpected FirClassLikeSymbol null for class org.jetbrains.kotlin.fir.symbols.impl.ConeClassLikeLookupTagImpl"

Describe the solution you'd like

Ouf of the box support for Kotlin, as it has good support in spring where jackson is the default.

hi! Those parsing errors will indeed prevent any changes to the associated files.

We're right now taking another look at our Kotlin parser in the following parallel efforts

• Support for Kotlin 2.2.0 Projects rewrite#6007
• Kotlin 2 rewrite#5963
• WIP: Use IR for KotlinParser instead of PSI/FIR rewrite#6325
• Add support for Kotlin 2.x rewrite#5575

I suggest you follow the above PRs, as any fix there will mean you should start to see changes here as well.

As there is no fix specific to this rewrite-jackson repository I'll already go ahead and close this issue. 🙏🏻
