I just built an annotation processor that generates a builder class for my classes annotated with

@DataBuilder

, my classes annotated with this annotation are located in

com.my.package.model

and the generated builder class is also located in the same package

com.my.package.model

but in the generated directory of course

build/generated/source/kapt/debug/com/my/package/model/MyModelBuilder.kt

, I can use these generated classes fine inside of my model classes(written in Kotlin) BUT I cannot use the generated

MyModelBuilder

Kotlin class inside of a java class as a class member

package com.my.package.home;
import com.my.package.model.MyModelBuilder;
public class Home {
    MyModelBuilder builder; // <=== AS recognizes the class, but I'm having an compilation issue
}

AndroidStudio recognizes the class, but I’m having this compilation issue

com/my/package/home/Home.java:4: error: cannot find symbol
MyModelBuilder builder;
           ^
  symbol:   class MyModelBuilder
  location: class Home

it’s weird because I can use this generated builder class only inside of methods, this code works fine

package com.my.package.home;
import com.my.package.model.MyModelBuilder;
public class Home {
    public void hello() {
        MyModelBuilder builder;
    }
}

could somebody here help me to understand this behavior? In advance, thanks!

Is it possible to obtain parameter init value in kapt? For example for

class User(var age: Int = 18)

get

value.

Is there a quick hack I can do to get kapt to tell me how much time is spent for each annotation processor? I.e. I want to know which processors of the ones we use are the most expensive

Getting this error when creating a custom

DataBindingComponent

inside a library module which is being used from an app module (in an android project):

e: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class <redacted>.CustomComponent, unresolved supertypes: android.databinding.DataBindingComponent

Is this a bug in kapt?

Kapt is failing with

e: Unknown option: infoAsWarnings

with

1.2.60-eap-44

. Anyone else seeing this?

@yan any specific reason for choosing

IsolationMode.PROCESS

? Maybe could have a flag to use

IsolationMode.NONE

Dagger works fine with multiple modules in fact you can use this example. My company is building a completely open source app for the art institute of Chicago: github.com/art-institute-of-chicago/aic-mobile-android I do most of the code reviews and we welcome all contributions once development slows down

🐛

kapt

used as an execution in

kotlin-maven-plugin

breaks IntelliJ's

pom.xml

parsing with Kotlin version

1.2.61

and IntelliJ version

2018.2.2.

Source folders are not marked correctly upon reimporting the maven project, it only marks kapt's generated source directory as source.

Is there a way to make IntelliJ see the generated files in

Is there something else for that then, or is it just impossible?

Is there a trick to getting kapt working with Java 10+? I have a simple Gradle projects that works with 8 and 9, but not 10 or 11.

hey everyone, in the Kotlin 1.2.60 announcement post it was said that the plan was to make

kapt.use.worker.api

enabled by default from Kotlin 1.2.70. Did it happen? Is it now the default?

Does anyone have recommendations on libraries/articles that covers annotation processing of properties and objects? Is there any way to utilize Kotlin Reflect from Element/TypeElement/etc?

Hello guys. During the build I get the following error:

> Task :app:kaptGenerateStubsDebugKotlin
e: error: cannot access Retrofit
  class file for retrofit2.Retrofit not found
  Consult the following stack trace for details.
  com.sun.tools.javac.code.Symbol$CompletionFailure: class file for retrofit2.Retrofit not found

The problem is that that class is present inside the following dependency:

implementation "com.squareup.retrofit2:retrofit:$retrofit_version"

When I switch from

implementation

compile

, the error disappears. What could it be?

Is there a way in kapt to get a hold of the structure of a function literal with receiver? When I try to extract info from

TypeElement

or the Kotlin Metadata library by @Eugenio for a function of the shape:

A.() -> B

it always shows up as

Function1<A, B>

but I have not found a place or API that denotes the declaration of such function as being the type of a receiver function.

Hi, currently I'm facing https://stackoverflow.com/questions/53289265/invalid-method-declaration-in-kotlin-enum-class-building-with-gradle-wrapper I think. We migrate our build chain to JDK11 though so a fallback to Java 8 is no real option. My error is

> Task :kaptGenerateStubsKotlin
e: …/Condition.java:16: error: invalid method declaration; return type required
        Condition() {
        ^

with an enum class like

enum class Condition {

    EXACT {
        override fun evaluate(actual: Set<String>, expected: Set<String>) = actual == expected
    },

//....

    abstract fun evaluate(actual: Set<String>, expected: Set<String>): Boolean
}

My build setup is

➜ gradle -v

Hi, Is there a way in kapt or by other means through Kotlin reflection or @Eugenio metadata lib to access the

KDoc

of a class and its functions programmatically? I looked in both APIs and could not find any references to the content about kdoc.

Tried clean and even clean build caches and restart android studio but it didn’t help. Is there any way to clean kapt cache?

if running the task fixes it.. how about making some task depend on

kaptKotlin

or however its called ?
