How can I configuration spring-boot-configuration-processor when I would like to change from KAPT to KSP? I get every time error

Issue

Basic problem, kapt is in maintenance mode. So I would like to change to ksp. In theory, it’s the equivalent of faster like kapt. The changing option is not clear.

I did:

This was

plugin {
   ...
   kotlin("kapt") version "1.7.20"
   ...

replaced by

plugin {
   ...
   id("com.google.devtools.ksp") version "1.7.20-1.0.7"
   ...
}

and there were

annotationProcessor("org.springframework.boot:spring-boot-configuration-processor")
kapt("org.springframework.boot:spring-boot-configuration-processor")

replaced by

annotationProcessor("org.springframework.boot:spring-boot-configuration-processor")
ksp("org.springframework.boot:spring-boot-configuration-processor")

So, when I build project I got below error:

> Task :kspKotlin FAILED
e: [ksp] No providers found in processor classpath.
e: Error occurred in KSP, check log for detail

I’ve been mining the internet for almost two days, but I still haven’t found a solution to this problem. If anyone knows, I will be very happy! 🙂

Solution

KSP is not a direct replacement to kapt. Changing one name to another won’t do the trick.

spring-boot-configuration-processor wasn’t built to work with KSP, so this line

ksp("org.springframework.boot:spring-boot-configuration-processor")

won’t do anything.
