A modern programming language that makes developers happier.

kotlinlang

We have several old Java projects using Lombok that we'd like to convert to Kotlin. We used the @Builder-annotation extensively and it's not yet supported by Kotlin. Unfortunately converting this code manually turned out to be too much of a hassle. If you're in a similar situation, maybe vote up the youtrack ticket: <https://youtrack.jetbrains.com/issue/KT-46959?_gl=1*q24pg*_ga*NDY2MzY3ODA3LjE2MjY2NzUwNDU.*_ga_J6T75801PF*MTYyNjY3NTA0NC4xLjEuMTYyNjY3NTEwMy4w&amp;_ga=2.20803896.1078897134.1626675045-466367807.1626675045|https://youtrack.jetbrains.com/issue/KT-46959?_gl=1*q24pg*_ga*NDY2MzY3ODA3LjE2MjY2NzUwND[…]_ga=2.20803896.1078897134.1626675045-466367807.1626675045>

Dunno if it’s any use to you, but when we first migrated to Kotlin I wrote an annotation processor to generate builders from Kotlin data classes -&gt; <https://github.com/Masabi/kotlinbuilder>

in the short term, delombok might be a workable hack?

I also wrote an annotation-based builder generator: <https://github.com/ephemient/builder-generator>

but apt-based approaches will always have some differences to lombok

I did do some digging into lombok-compiler-plugin, and I think the trickiest thing about `@Builder` is that it creates a whole new nested class, which the compiler's SyntheticJavaResolveExtension just isn't set up to allow for
