    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
    Copy code
    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
    Copy code
    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
    Copy code
    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 
    18
    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):
    Copy code
    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?

    @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.

    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:
    Copy code
    > 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
    to 
    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
    Copy code
    > Task :kaptGenerateStubsKotlin
e: …/Condition.java:16: error: invalid method declaration; return type required
        Condition() {
        ^
    with an enum class like
    Copy code
    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
    Copy code
    ➜ 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.
