Support OpenApi annotations defined in standalone modules

[f1qwase]

we store common API models shared between multiple projects in a separated api project

but annotations of models from that project are totally ignored by annotation processor when annotation processor runs on a project that imports api project (using implementation(project(":api")))

I guess it may be limitation of kapt, because both Gson that uses reflection and koltlinx.serialization that is compiler plugin don't have that problem and can read their annotations from imported projects

is there a way to fix it?

thank you

Do you mean that entity annotations:

• https://github.com/javalin/javalin-openapi/wiki/3.-Features#openapi-entities

Does not work if they're not declared in the processed module or you'd like to support the @OpenApi annotation used in 3rd party modules?

I mean that entity annotations don't work if they are used on a model that declared in one module and used in another one. I have a structure like that:

project
  moduleX
     src
        ModelA.kt
     build.gradle.kts
  moduleY
     src
        ModelB.kt
     build.gradle.kt
  build.gradle.kts
  settings.gradle.kts

where files ModelA and ModelB are like

// ModelA.kt

@OpenApiName("NotWorking")
class ModelA

// ModelB.kt

@OpenApiName("Working")
class ModelB {
   val modelA: ModelA,
}

// settings.gradle.kts
include(
  "moduleX",
  "moduleY",
)

and moduleY/build.gradle.kts imports moduleY like

// moduleY/build.gradle.kts

dependencies(
  implementation(project(":moduleX")
)

if I run moduleY:kaptKotlin gradle task it produces openapi-default.json like

{
   "schemas": {
      // should be "NotWorking"
      "ModelA": {
         "type": "object",
      },
      "Working" {
         "type": "object",
         "properties": {
            "modelA": {
               "$ref": "schemas/components/ModelA"
            }
         }
      }
   }
}

sorry for so much details, I don't understand how gradle works and might provide unnecessary details

Could you try to use the latest snapshot? Those annotations should be preserved in compiled sources, so annotation processor should be able to find them in binary files :)

@dzikoysk I tried the latest commit (51d2405) and it works
thanks a lot!
but then I checked previous one (dd2ebd9) with BINARY annotations and it works as well, so may be BINARY retention is enough
I guess that different testing results here and in #125 may be a result of some sort of caching so I cleaned all gralde caches I could find before testing
