i did.. now i am getting this: e: /home/nikky/dev/fabric/config/build/tmp/kapt3/stubs/main/config/CottonConfig.java:6: error: incompatible types: NonExistentClass cannot be converted to Annotation

[gildor]

So now it looks that your config is correct, Kapt is running, but you have some issue on classpath

[gildor]

Add this to gradle.properties to get real error message instead of NonExistentClass
kotlin.incremental.usePreciseJavaTracking=true

[gildor]

Also, are you sure that you have those annotation in AP classpath?

[Nikky]

i have them in a seperate subproject that i added to implementation and kapt

[Nikky]

and the annotationprocessor subproject also depends o nthem

[Nikky]

and i fixed this error.. now it works.. but does nothing ?

[gildor]

So problem solved? What do you mean does nothing? As I see your AP just doesn't generate any code

[Nikky]

it should print me the annotation it processes.. but no logging

[gildor]

Should print where? I don't think that you will see those logs in Gradle on default log level

[Nikky]

i did when i was using annotationProcessor

[gildor]

Just to check that your code runs, add assert there or write to some file

[Nikky]

assert does not fire.. and i have to go.. seeya later

[gildor]

But error from above was definitely from kapt. Maybe you changed some config

[Nikky]

there was the annotation i wanted in the subproject but there was a file in the main project i nthe same place, ssame name but contents commented out

[Nikky]

that messed it up since that loaded first

[Nikky]

so now i pipe stdout into a file and get a log that way.. and i see that kapt gives me 0 classes..

roundEnv: [errorRaised=false, rootElements=[], processingOver=true]

[gildor]

Are you sure that have classes annotated with this annotation?

[Nikky]

it works on java classes when i run it via anotationProcessor and remove the kapt plugin

[Nikky]

i pushed my current progress to here.. its just PoC project anyways..
https://github.com/NikkyAI/cotton-config

[Nikky]

annotations are in annotation
the annotation processor in annotationProcessor

[Nikky]

the root project uses the annotation processor

[Nikky]

thats where i use it: https://github.com/NikkyAI/cotton-config/blob/7aff95d0879aad2381e0e2d4fe5b87fb187cbd05/src/main/kotlin/config/KottonKonfig.kt#L9

those and more are marked as supported on the annotation processor

[gildor]

Maybe you have some problem with auto factory execution, register your processor manually instead using auto factory, maybe problem with nested kapt run

[gildor]

Also check that AF actually generated metainf for you

[Nikky]

it does .. i checked.. but i gues i will just copy that into the META-INF then

[gildor]

I saw your message that now everything works, but you just has problem with logging

[Nikky]

it seems like i was not noticing before. .the file i thought was getting log written to did nto change.. kapt seems to be unale to write to anywhere outside of the provided "kapt.kotlin.generated" option

[Nikky]

now i am trying to find a way to have the annptation processor work the same for running with annotationProcessor and with kapt

[Nikky]

i just want to write resource files anyway.. no java or kotlin sourcefiles

[gildor]

Not sure what you mean, because all annotation processors that I know written for APT and don't have any kapt specific changes, because this is a way how kapt works, it's transparent for AP

[gildor]

What kind error do you have if you try to write to file outside of this dir?

[Nikky]

e: [kapt] An exception occurred: java.io.IOException: No such file or directory
	at java.io.UnixFileSystem.createFileExclusively(Native Method)
	at java.io.File.createNewFile(File.java:1012)
	at config.ConfigProcessor.process(ConfigProcessor.kt:72)
...

[Nikky]

using normal annotationprocessor i can write anywhere

[Nikky]

also apparently kapt does not add any other filetypes to the jar.. only .kt files are getting compiled in.. i might need some extra tasks to move files around then

[gildor]

This is not a job of kapt to add files to jar, only generate + kapt has own source set for kotlin generated files

[gildor]

But not anything else, you have to write to some existing source set

[Nikky]

well the problem still stands.. kapt does process nothing even though i use the annotations in java and kotlin code..

for now i tried to look at google's autojson code since i know that one worked in kapt
but for some reason the same code for opening a FileObj throws for me
val fileObj = processingEnv.filer.createResource(StandardLocation.CLASS_OUTPUT, "", "config/test.json")

[Nikky]

throws this:

e: error: FATAL ERROR: javax.annotation.processing.FilerException: Attempt to reopen a file for path /home/nikky/dev/fabric/cotton-config/build/tmp/kapt3/classes/main/config/test.json
  	at com.sun.tools.javac.processing.JavacFiler.checkFileReopening(JavacFiler.java:535)
  	at com.sun.tools.javac.processing.JavacFiler.createResource(JavacFiler.java:431)
  	at config.ConfigProcessor.processImpl(ConfigProcessor.kt:100)
  	at config.ConfigProcessor.process(ConfigProcessor.kt:43)
  	at org.jetbrains.kotlin.kapt3.base.ProcessorWrapper.process(annotationProcessing.kt:99)

[Nikky]

so for some reason i am getting FIleObjects that are not open for writing.. i have to compare this to annotationProcessor behaviour

[Nikky]

the lack of logging is really annoying me..though i can attach a debugger and found it it does run.. 2 times in fact i guess the last one is for test sources and ofc it finds nothing there

[yan]

Try the correctErrorTypes option: https://kotlinlang.org/docs/reference/kapt.html#non-existent-type-correction.

[Nikky]

it works now.. assuming all annotations are actually available to both the annotation processor, compilation and kapt configuration
but that does not fix the logging right ? or the fact that the kapt plugin in gradle hides stdout or blocks filesystem access outside of the "intended" folders ?

[Nikky]

it would be really nice if i did not have to write a logfile into the produced jar.. i might need a extra gradle taks just to remove it again on release

[gildor]

Why do you write logfile to jar?

[Nikky]

because i cannot write to stdout the messager provided by the annotation processing envirnment does nothing and i cannot write anywhere else

[Nikky]

usually you would expect this to work right ?
processingEnv.messager.printMessage(Diagnostic.Kind.NOTE, msg) it seems to be the right thing to do.. most annotation processing libraries like google's autoService also uses this.. but in kapt they are not printing anything either..

[gildor]

Did you check info log level?

[Nikky]

ok that shows the logs at least.. i guess there is no reason for a logfile then
