What would be the best practice for consuming generated classes by KSP? For example to create the instance of them, in JVM the app can leverage reflection, but what about Native/JS? Precondition: if we do not want users to execute ksp task once when interacts with generated classes.

Hi 👋 I’m looking for a way to generate a class from a json file before/as part of my build. Would KSP be a viable way to do that?

I have the following multi module project (see image) which works just fine. Sources are beeing generated/added and the app works just fine. Now I wanted to use the processor in a new app, and added A, B and C to the project, using

implementation(files("libs/B.aar"))
implementation(files("libs/A.jar"))
ksp(files("libs/C.jar"))

I'm getting the following error during kspDebugKotlin:

java.lang.NoClassDefFoundError: _*Class from module A*_

What am I doing wrong? EDIT: When adding A and B to KSP like so:

ksp(files("libs/C.jar", "libs/A.jar", "libs/B.aar")

It does find the class from module A. Now it is still missing a dependency which is used in A and my current project. EDIT 2: After adding every dependency with ksp() it is working now.

Hi everyone, I have an android project set up with ksp. When I am building the debug and release version in succession, I am getting a compile-time error saying that duplicate declarations are present. The issue is that ksp is building the same code under the debug folder and in the release folder. How can I solve this? I am attaching a screenshot for reference.

I updated from ksp 1.6.10-1.0.4 to 1.6.21-1.0.5 and

kspMetadata

configuration isn't found anymore. Is

kspCommonMainMetadata

the correct replacement?

Hello - Small question - when I use

getSymbolsWithAnnotation

with multiple deferring Annotation for a Class target. Is it suppose to pick up only the first?

Given a KSFunctionDeclaration and a KType for a function, e.g.

(String) -> Unit

, is there an easy way to check if the KSFunctionDeclaration matches that signature?

Just an Observation I'd like to share - if I generate for example for commonTest something, neither

getNewFiles

nor

getAllFiles

picks them up - I believe this has to do with the fact that meta/shared sources (except commonMain) cannot be declared for KSP right?

Hi there, for a Kotlin/JS app, I’d like to show sample code on a web page. This sample code is the body of a lambda (but could also be refactored to a normal function / method. Currently I copy/paste the sample code into a multi line string constant and use that constant to show the sample code on the web page. Is it possible to mark the function containing the sample code with an annotation and use a KSP processor to extract the function body and generate a string constant with that exact source code? Ot is this only possible using a compiler plugin?

Is there any plan to address https://github.com/google/ksp/issues/965 anytime soon?

Hey another week - another question. So please have a look at the thread.

I created a tool to aggregate Kotlin Symbols for multi-modules development in compile-time, based on KSP. For instance, to gather all implementations of an interface across multi-modules, and later register/call them together in somewhere. https://github.com/2BAB/Koncat

Does anyone have any idea why default value for annotation argument is not being retrieved?

// annotation
@Target(AnnotationTarget.FUNCTION)
@Retention(AnnotationRetention.SOURCE)
public annotation class Showcase(
  val katalog: String = "katalog"
)

// application in sources
@Showcase
fun testTarget() {}

// usage in processor
  private fun KSAnnotation.showcaseData(): ShowcaseVisitor.Data {
    arguments.first { it.name?.getShortName() == "katalog" }.value!! as String // throws NPE
  }

I'm on ksp:1.6.21-1.0.5. I've also verified that the KSAnnotation at least contains the argument by that name

It seems KSP is taking up a fair bit of memory, causing my github actions runner to crash. What should I do to reduce this? Here's the full error log:

It's possible to use ksp with hilt instead of kapt?

In case you are looking for it, kotlin 1.7.0-RC was released earlier today, and here is the KSP 1.0.5 release for Kotlin compiler 1.7.0-RC

Would it be possible to generate code from one source set into another via a KSP processor? Example being:

@Parcelize data class Foo(val bar: String): Parcelable

would generate something like

@EnforceImpl abstract class FooRoundTripParceling {...}

into the androidTest source set. Then I could have a different processor watching for annotations to pair the impl with a generated template. I assume generating some sort of resource file and doing a processor or gradle task that operates on the generated resources would be the only way to do something like this.

https://github.com/Jintin/KBuilder Create a tool to auto-generate builder pattern using ksp, hope this can showcase the power of ksp over annotation processing

I'd like to completely parse a kt file, I can see all the top-level declarations in this way:

resolver.getAllFiles().first { it.fileName == "terraform.kt" }.declarations

but for functions, I can't "enter" and see the body, that is all the declarations inside is it a visitor mandatory?

Does anyone use this project for testing? https://github.com/tschuchortdev/kotlin-compile-testing I tried to use this library but my pet example class is not recognized by the processor. (When I use "real" ksp processing it works as expected.) Example test file: https://github.com/kotlinw/kotlinw/blob/main/kotlinw-immutator-processor/src/test/kotlin/kotlinw/immutator/processor/TestKsp.kt Thanks.

What should I do to see KSP

<http://logger.info|logger.info>()

messages while compiling in Idea? Messages by

warn()

and

error()

is displayed on the console but

info()

is not. Thanks.

Is there a way to change the KSP task input dependencies? Specifically we have modules A, B and C with C depending on A & B, but declaring only methods using A. KSP still waits for both A & B to compile though. As a workaround we currently have a submodule of C, which declares just A as a dependency containing a Sync task which copies all the parent kotlin sources to a temporary directory, then have the KSP task run with that.

I am working on fixing multiplatform issues with the KSP Gradle plugin. Details in 🧵.

Create another side project to build simple factory pattern easily leverage on ksp https://github.com/Jintin/Kactory/

I have a multiplatform multimodule project with KSP, where I'd like to generate classes in common code. In the docs there is a part:

dependencies {
    add("kspMetadata", project(":test-processor"))
...

In my project there seems to be no kspMetadata configuration:

Configuration with name 'kspMetadata' not found.

What is the correct configuration? Thanks. Environment: Idea 2022.1.2 CE, Kotlin 1.6.21, KSP 1.6.21-1.0.5

I'm trying to convert a library from kapt to ksp. In kapt I had a very useful kotlinpoet

TypeElement.toTypeSpec(ClassInspector)

extension. Then generating the code from the original TypeSpec was a breeze - e.g. just mapping original functions to their modified generated equivalents. I can't find an equivalent in KSP world, I would assume because there is no equivalent ClassInspector. I guess I could modify my generator classes to not rely on TypeSpec but rather something more abstract, but it would be super convenient if there was something similar. What am I missing?

Is there a way to let ksp generate tests? I want to generate a test based on my main source set.

Hello there 👋 is there a way to scan sources accross multiple gradle modules while using

resolver.getSymbolsWithAnnotation(...)

?

Hello! I have a class that I want to process and create a metadata class based on the field types. This class has an enum field. The enum declaration is located in a different gradle module. The problem is that the

KSDeclaration

of this enum does not contain the

ENUM

modifier (It has only the following modifiers:

PUBLIC

,

FINAL

). If I move the enum class into the same gradle module then the

KSDeclarartion

will have the correct modifiers. Is there some sort of limitation with multi-module projects or is it a bug?
