Question

I run above kotlin mapstruct project with maven but it emits below error.
Exception in thread "main" java.lang.RuntimeException: java.lang.ClassNotFoundException: Cannot find implementation for org.mapstruct.example.kotlin.converter.PersonConverter
at org.mapstruct.factory.Mappers.getMapper(Mappers.java:61)

It seems annotation processor is not working even I enabled annotation processing in the Settings.
https://kotlinlang.org/docs/kapt.html#using-in-cli
The Official kotlin document says:
Please note that kapt is still not supported for IntelliJ IDEA’s own build system. Launch the build from the “Maven Projects” toolbar whenever you want to re-run the annotation processing.
(related issue: https://youtrack.jetbrains.com/issue/KT-15040)
So I tried to conduct kapt manually.
However the output folders are still empty.
What's wrong with me?
I was able to do annotation processing in Java with Maven before.
Thanks in advance.

Answer 1

I found the answer.
Just push compile button in Maven project or mvn compile in command
before running your application whenever you need the annotation processing.
