Hello I m trying to define a gradle convention plugin with p

Question

Hello I m trying to define a gradle convention plugin with parameters on a KMP project and I want to be able to enable platforms on demand something like ```plugins id com deezer kmp convention plugin version 0 1 0 kmpp platformJvm set true ``` but I ve a couple of issues when I use a Property from an abstract Extension the value is accessible only if I use `afterEvaluate` I think the multiplatform plugin expects to be configured in the configuration pass and what I do in the afterEvaluate is too late Is it possible to listen Property changes so that I can apply multiplatform plugin when the value is set I suppose it s still the configuration phase Any help or idea is much appreciated

```public fun Project kmpp action Action lt KMPPExtension gt = Action action invoke the configure here ```

Javier · Answer

rename the real extension creation name to something like InternalKmpp

mbonnin · Answer

Is kmpp your own extension

Javier · Answer

I think so if not my approach is useless

Grégory Lureau · Answer

Yes it is Thanks for the trick I ll test that right now

Grégory Lureau · Answer

Yay Big thanks < Javier> and < mbonnin> I had to adds the sourcesets configuration as a 2nd parameter of the extension function due to the restriction of KMP to have at least one platform defined but it s fine for me Just if someone found this conversation here is the result ```public fun Project kmpp action Action lt KmppConventionPluginExtension gt = Action sourceSetsConfigure Action lt NamedDomainObjectContainer lt KotlinSourceSet gt gt = Action action the val ext = extensions kmppExt as KmppConventionPluginExtension plugins apply org jetbrains kotlin multiplatform val kotlin = extensions getByName lt KotlinMultiplatformExtension gt kotlin if ext platformJvm get kotlin jvm More configuration sourceSetsConfigure kotlin sourceSets ``` I was expecting to be able to use `kotlin ` directly after my extension function but it s tricky in my case if the multiplatform plugin is applied in the `Plugin` apply method it fails because there is no targets and if it s in the extension function then `kotlin ` is not available in the build gradle kts as the plugin has not been applied yet

Javier · Answer

I haven t it without the source set part

Javier · Answer

you probably can get rid of them for sure

Grégory Lureau · Answer

If I ve always one target enabled by default I don t need this trick for sure but that s not the case on my current project Also limiting to the sourceSets seems like a good idea for now but I guess I ll have to experiment more before seeing some limitations

Javier · Answer

I haven t added a default target and I get it working

Javier · Answer

I even configure the source set to remove `src` part with no issues

Javier · Answer

If I remove all targets in that extension KMP plugin fails with the typical message that you need at least one target

Grégory Lureau · Answer

Oh yes ok I presume it s because you have the kotlin block in the method itself I was trying to use it after the ext func `hubdle`

Javier · Answer

no

Javier · Answer

that kotlin it is not the default kotlin

Javier · Answer

it is a custom one

Javier · Answer

this doesn t exist in the default Kotlin extension ```kotlin multiplatform ```

Grégory Lureau · Answer

How do you define the sourceSets

Javier · Answer

that is the real Kotlin extension

Javier · Answer

which I would avoid in my projects it is only a fallback for complex use cases

Javier · Answer

nothing special

Grégory Lureau · Answer

Okay thanks it makes sense then I was not clear about the execution order Thanks for your snippets I ll work more on that star struck pray

Javier · Answer

you re welcome slightly smiling face

Javier · Answer

I am going to remove the marker so the nested kotlin extension the original Kmp extension renders as yellow instead of that purple
