//Module A

//Module B with KSP Processor
class MyKotlinClass(@MyJavaClass.MyAnnotation val myProp: Any)

Hi! In my KSP Processor I’m trying to resolve

KSTypeReference

of annotation type

MyJavaClass.MyAnnotation

which I face during analysis of `MyKotlinClass`’s constructor and for some reason it could not be resolved (

KSType#isError

returns true). If I move

MyAnnotation

to the top-level everything works fine. I am not sure how I can debug this issue, any ideas? =\

Hello! We released a small library for converting enums to primitives and vice versa with the help of KSP. If someone wants to use it or give a feedback here is the link https://github.com/bluegroundltd/enum-convertible

hey, I noticed some behaviour when running gradle profiler benchmark that I am not sure if it is the desired one. kotlin daemon memory usage and live threads keep increasing when ksp is enabled. The only library using ksp in the project is room and I run the benchmark 50 times to check if the memory usage would stabilise at some point as I am just compiling the app over and over (without changes in the code) and as you can see by the image below the memory usage keeps increasing for each iteration of the benchmark. These charts are from a sample project that I can share and the GC starts to be noticeable around the 25th compilation for this project, but much earlier for other configs/projects. I would expect the amount of memory used to be stable around the 4th or 5th compilation. Is it normal? Should I open an issue at ksp repo ? room issue tracker? jetbrains issue tracker?

New to KSP here so I got a question. I am building something in KSP to generate some code according to some annotations. I got the KSP code in a separate module called

:kspProcessors

inside the project, and I am importing it into my module (let’s call it

:app

) where I want the code generated with

add("kspJs", project(":kspProcessors"))

,

add("kspAndroid", project(":kspProcessors"))

and

add("kspIosX64", project(":kspProcessors"))

. Thing is, inside my KSP, code, it’d be very convenient to have access to the classes that exist inside my

:app

module, to more easily reference them in the code I generate. But would I not then introduce a circular dependency if

:kspProcessors

was depending on

:app

with

implementation(project(":app"))

and had

:app

depend on the ksp module as I am describing above? Would I need to keep the KSP code inside the same module? Maybe there’s no circular dep if one depends on the other using

implementation

and the other using

ksp

? I do not know if I am wording my question as well as I could’ve since I am totally not familiar with how to work with KSP in general, so please ask clarifying questions if I can make something more understandable.

I’m having an annotation that looks like this:

annotation class ComposeRenderer(
  val forComponent: KClass<out Component>,
)

I can’t figure out if it’s be possible to get in some way what the KClass would be to get it’s name, package and if it has any generics, and I am having a hard time looking into the documentation myself in order to help myself basically. And the questions existing online on SOF or whatever are quite sparse for KSP. Is there some place where people tend to go when they have KSP questions that I should be aware of?

Hello everybody 🙂 is there in the KSP opportunity to get all subtypes (subclasses/subinterfaces) for some

KSCLassDeclaration

in case if that declaration is no sealed?

Hello my people! We run an OWASP dependency analyzer. According to this analyzer, the KSP plugin and the room-ksp has a vulnerability:

room-compiler-processing-2.4.3.jar (pkg:maven/androidx.room/room-compiler-processing@2.4.3, cpe:2.3:a:processing:processing:2.4.3:*:*:*:*:*:*:*) : CVE-2018-1000840
symbol-processing-1.7.10-1.0.6.jar (pkg:maven/com.google.devtools.ksp/symbol-processing@1.7.10-1.0.6, cpe:2.3:a:processing:processing:1.7.10.1:*:*:*:*:*:*:*) : CVE-2018-1000840

Am I correct that we can safely ignore this? I assume the generated code will not be affected by this. (we are building an Android application so we care mostly about runtime safety)

Did anyone use or anyone knows if KSP for processing Kotlin scripting source files?

How should I proceed to get all the properties from all the classes annotated with a given annotation and create an enum out of them? The example I followed so far deals with one annotated class at a time, is it possible to create a file when processing the first file and add values to it in the following classes?

How are ksp gradle tasks included into other assemble tasks? My library relies on kspCommonMainMetadata being run. For me it's run for KMM's embedAndSignAppleFrameworkForXcode but for another person it's not. How can I debug such an issue?

I see warnings like this from JavaCompile tasks later, would it be worth filing an issue to not generate empty dirs?

While using KSP with multipaltform my project cannot resolve classes inside the

kspcache

however it works perfectly fine on the first run when the classes are located at

build>generated>ksp

any idea why this happens and what the fix might be?

A simple introduction and example of KSP, hope it can help any of you who are new to it. Feel free to comment if you have any suggestion. Thanks! https://medium.com/google-developer-experts/ksp-for-code-generation-dfd2073a6635

When I enable KSP on a KMP project (Android/JS/...) and I run only

compileTestKotlinJs

it somehow triggers the task

kspReleaseUnitTestKotlinAndroid

. Any idea why it's linked? Is it an expected behavior?

Is there a better way to check that the class of each element of a list is annotated?

return (argument as Array<KClass<*>>)
    .toList()
    .all {
        resolver.getClassDeclarationByName(it::class.java.simpleName)
            ?.filterAnnotations<CrossViewEvent>()
            ?.toList()
            ?.isNotEmpty() ?: false
    }

is it possible to convert a

KClass

to a

KSType

without using the resolver?

Hello! Does KSP have possibility to iterate through all symbols in all module dependencies?

Is it possible to create a file in an external folder other than the build folder through KSP? I tried this but it didn’t work. (Using the

java.io.File

package)

Hi! I’m looking at the weird issue right now. I have a module with mixed kotlin\java code and in this module I have two java classes in two different packages. They both have the same annotation and they both passing a nested class to annotation’s

Class<?>

argument. And for some reason for one class KSP resolves class type passed to the argument successfully and for another class KSP returns ERROR TYPE. It looks super weird since both annotated classes very similar, both have the same visibility and implement same interfaces. The only difference is the package. Class passed to a

Class<?>

argument in both cases is being nested inside annotated class itself. I’m confused and not sure how to even approach debugging here =\

Hi there, is it possible to get the name of the constants an enum declares? This isn't possible with the traditional Java annotation processing but I was curious if it's something KSP might support.

Do we have any plans for the next release of ksp for the current stable version of kotlin?

Has anyone tried to update AndroidManifest.xml using ksp ? Any github repo with it?

Hi, this might be me that has missed something fundamentally about KSP, but I was wondering; Is there a way to get the annotation of an annotation that is in a different module than the element that is annotated? 🤔 I can get the base annotation from the

XRoundEnv.getElementAnnotatedBy

if I know the qualifiedName of the annotation in question. However, if I use the typeName of the annotation that I get from

XRoundEnv.getElementAnnotatedBy

to fetch the annotation that the first annotation is annotated with, it only works if they are in the same module. Does anyone know if this is possible? 😄 Is it not working because I use the typeName form the first annotation?

I'm running into an issue where

declaration.getAllFunctions()

is not picking up functions though a type generated in a previous round, ie: If I have:

interface Source { fun targetFun() {} }
interface Generated : Source // this is generated in round 1
interface Target : Generated // this is processed in round 2

then

declaration.getAllFunctions()

won't include

targetFun()

interestingly enough walking up to the interface manually does work

((declaration.superTypes.first().resolve().declaration as KSClassDeclaration).superTypes.first().resolve().declaration as KSClassDeclaration).getDeclaredFunctions()

I am getting

UnknownPluginException

for KSP

org.gradle.api.plugins.UnknownPluginException: Plugin [id: 'com.google.devtools.ksp', version: '1.7.10-1.0.6'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'com.google.devtools.ksp:com.google.devtools.ksp.gradle.plugin:1.7.10-1.0.6')

Following is the configuration added in my android project

app/build.gradle

plugins {
    id("com.android.application")
    id("kotlin-android")
    id 'com.google.devtools.ksp' version("1.7.10-1.0.6")
}

dependencies {

    implementation "androidx.room:room-runtime:$room_version"
    ksp "androidx.room:room-compiler:$room_version"
}

Hi there, it looks like KSP supports only

KSClassDeclaration

,

KSFunctionDeclaration

and

KSPropertyDeclaration

. Do you know whether there is a plan to also support annotations with

@Target(AnnotationTarget.EXPRESSION)

? Thanks!

I think there is a bug In KSP’s method

com.google.devtools.ksp.UtilsKt#isVisibleFrom

. When it looks at protected visibility it treats it as visible if it is in the same package with a class passed to

isVisibleFrom

it works for java but doesn’t work for kotlin, because in kotlin protected is only accessible from the class inheritors.

Can KSP see the code from dependency modules, or libraries? Or can it only alter the current module’s code?

Hello, I have an annotation that takes a KClass, I wanted to access information of that class in processor but it's not in class path, was wondering if theres a way to work around this? Do I have no choice but to provide the class information I need in annotation instead

I’m trying to access my generated code from unit tests so I added this

sourceSets.commonMain {
    kotlin.srcDir("$buildDir/generated/ksp/commonMain/kotlin/")
}
sourceSets.commonTest {
    kotlin.srcDir("$buildDir/generated/ksp/commonMain/kotlin/")
}

But I still get a

Source file or directory not found

. What should I do to fix that?
