Does anyone know where to find documentation on how to write a Kotlin compiler plugin? Or at least some general information about the architecture of those plugins. I am currently using JSON-B (Yasson impl) in my project but it can only instantiate a data class when I annotate the constructor and all parameters (providing the parameter name). As a fallback I could of course use the noarg compiler plugin but I was wondering if annotating constructor parameters using a compiler plugin is possible.

there is no documentation. compiler plugins are an unsupported and intentionally undocumented feature

Thanks for the info, I'll see if the noarg plugin will do for now 🙂

Actually you're better off contributing to Yasson impl that to Kotlin compiler, this same problem in Jackson was solved on Jackson side via Kotlin module you could take a look at it for inspiration. I don't know anything about Yasson impl though, so no idea if it's doable

Also Kotlinx.Serialization is good option, at least in the future And better to invest contribution effort to kotlinx.serialization than to a separate compiler plugin #serialization

Thanks for mentioning kotlinx.serialization, that is exactly what I was looking for. Didn't know something like that was already being worked on 🙂
