hi guys,

I am trying to add Kotlin support into my existing Java/Maven project
folks on the internet advice to execute kotlin-maven-plugin first and the maven-compiler-plugin

but what if I have in Java annotation processing that is generating some source files, how can I call those from Kotlin?

[nfrankel]

https://kotlinlang.org/docs/reference/using-maven.html#compiling-kotlin-and-java-sources

[nfrankel]

follow instructions there

[Alexey Anufriev]

this I have seen but still the guide has no info on java-annotation-processing, imagine I do the setup as it is stated there, but Kotlin compilation will fail as java-annotation-processing has not been executed yet thus no required java classes were generated

[nfrankel]

this links another page:
https://kotlinlang.org/docs/reference/kapt.html#using-in-maven

but this is annotation processing for kotlin, and in my case I have annotation processing for java

[nfrankel]

are you sure?
looks a lot like java is in here too

<sourceDirs>
  <sourceDir>src/main/kotlin</sourceDir>
  <sourceDir>src/main/java</sourceDir>
</sourceDirs>

I will try, thank you

[nfrankel]

i’m not saying it will work
i’m just saying it looks like it

[Alexey Anufriev]

sure, no problem

[nfrankel]

did it work?

[Alexey Anufriev]

kapt is not triggered if there are no koltin sources

[Alexey Anufriev]

that is what I am trying to overcome right now

[Alexey Anufriev]

in fact I made a PR for maven plugin, so as soon as this is merged then this scenario will work

[nfrankel]

great!
but i’m a bit surprised you were the first to have this issue

[Alexey Anufriev]

me too 😉
