I would like to create an extension function like ...

# gradle

[David Miguel]

I would like to create an extension function like this in my buildSrc module. However I cannot access implementation() , kapt(), etc extensions functions that are declared in the package org.gradle.kotlin.dsl from the gradle-kotlin-dsl-accessors artifact. Is it possible to have access to them from my buildSrc module? Thanks for you help.

fun DependencyHandler.implementation(dependencyNotation: Any): Dependency? =
    add("implementation", dependencyNotation)

[Javier]

You can't access to implemention because you are not applying the plugin in that file

[David Miguel]

yeah at the end I just copied pasted the functions that I needed

[David Miguel]

but it doesn’t feel very right to me. What I was wondering is if I can import the gradle-kotlin-dsl-accessors artefact somehow in my buildSrc module

[David Miguel]

so that I don’t need to duplicate code

[no]

those accessors are generated for one of the plugins which is applied to your project. you should have access to it if you apply that plugin to your buildsrc as well.

[David Miguel]

Hi Nelson, thanks for your answer 🙂
Which plugin should I apply? Currently I’m applying the kotlin-dsl plugin in my buildSrc, but still I cannot access those accessors.

[Javier]

kotlin("jvm") , or multiplatform, android, etc

[David Miguel]

thanks Javier. I’ve tried to apply the jvm and android plugins but then it doesn’t even compile the build.gradle.kts file from the buildSrc module

[David Miguel]

do you have any clue why?

[Javier]

ah, android one is different, id("com.android.library"), try kotlin("jvm")

[David Miguel]

hmm same problem with jvm, it cannot find the declarations for these accessors

[Javier]

Ah, I didn't see the screenshot, that implementación should work with only kotlin dsl

[Javier]

I have this in my buildSrc/build.gradle.kts

[no]

are they just red in the ide, or does the build fail as well?

[David Miguel]

yeah the build fails as well with this error

[David Miguel]

@Javier, with that config, do you have any function in your buildSrc that makes use of some of this accessors? Like this one

[no]

@David Miguel if you fix the typo in the dependency you requested, does the build still fail? builPd -> build

[David Miguel]

uhh

[David Miguel]

😅

[David Miguel]

let me retry

[David Miguel]

sorry the typo was introduced in the last retry. After removing it, I get the error I was getting before, that it cannot find those extensions functions

[Javier]

@David Miguel yeah, creating the extension function I shared some time ago

[David Miguel]

ahh I think we are not understanding each other hehe

If I declare the extension functions myself, it works fine 👍

But ideally, I would like to avoid having to declare those extension functions myself, and instead access the ones provided in the gradle-kotlin-dsl-accessors artefact. But that is what I don’t know how to achieve it (maybe is not even posible).

[David Miguel]

but it’s a minor thing, I’m happy declaring them myself. I was just wondering whether the other approach was posible

[Javier]

I can only get that function if I am creating a precompiled plugin and I am applying some plugin which includes it. I have to try @no solution to check if I can remove my own extensions.

[Javier]

I added it to buildSrc/build.gradle.kts and it is not working, I can't access to implementation in the extensions file

[Javier]

I tried to add the plugins inside dependencies { implementation(...) } in buildSrc dependencies but I cannot access to implementation functions in extensions too.

[no]

I think since these are generated accessors they are not part of the API. Being able to use them doesn't mean that these methods will be available when you ship your plugin. It is best to redeclare them.

[David Miguel]

thanks @Javier for trying it out 😊

@no that was one of my hypothesis, thanks for confirming! We’ll have to redeclare them for now
