Hello guys, I have a Kotlin-JVM lib published on Bintray ( let’s call it myLib ) and a Gradle plugin.

Plugin got myLib as dependency and example is using the Plugin, but I got

> Failed to apply plugin [id 'studio.forface.easy-publish']
   > Could not create an instance of type studio.forface.easygradle.publish.EasyPublishExtension.
      > Could not generate a decorated class for type EasyPublishExtension.
         > studio/forface/easygradle/internal/ConfigReadWriteProperty

ConfigReadWriteProperty is part of myLib and EasyPublishExtension is something like:

abstract class EasyPublishExtension @Inject constructor(project: Project) {

    var username by project("", propertyName = "bintray.user")
    
    private operator fun <T : Any> Project.invoke(
        default: T,
        propertyName: String? = null,
        envName: String? = null
    ) = object : ConfigReadWriteProperty<EasyPublishExtension, T>(
    ....

}

What is the problem here?

[no]

does it work if you remove project from the extension constructor?

[Davide Giuseppe Farella]

I think that’s not the problem, I followed this template
https://github.com/cortinico/kotlin-gradle-plugin-template/blob/master/plugin-build/plugin/src/main/java/com/ncorti/kotlin/gradle/template/plugin/TemplateExtension.kt

And error explicitly mention

studio/forface/easygradle/internal/ConfigReadWriteProperty

[no]

i see. how are you instantiating the extension? can you post a full stacktrace?

[Davide Giuseppe Farella]

Ouch. There’s a ClassNotFoundException actually

Here’s my full code, if can help

[no]

in which project is the plugin?

[no]

and in which project is the error?

[Davide Giuseppe Farella]

example

[no]

how does sample include the plugin?

[Davide Giuseppe Farella]

Actually from Gradle Portal

[Davide Giuseppe Farella]

( sorry for late replies, for some reason I don’t get notifications )

[no]

ah, so it is already published to gradle portal? is the library project that the sample depends on also published there?

[Davide Giuseppe Farella]

*the plugin depends on
Yes, it is published - I was not able to test it locally, it is my first Plugin, it was shipped as a library intended to be included in buildSrc, and it was working properly, so I was too confident 🙂 - The library it depends on is on Bintray

[no]

it seems like you are using the dsl project as both an included build and using the jar directly.
it is not published to bintray from what i can see

[no]

i would recommend making dsl a part of the plugin module first and then try separating it later

[no]

i would also recommend following the structure of Nicola Corti's project

[Davide Giuseppe Farella]

Oh yes, you're right! I've included it as a jar! That's the reason! That's not exactly what I wanted to do, I've just not been able to include as conventional way

implementation(project(":dsl"))

Is there any way to achieve that?

Also what's the difference in my structure? 🤔

[Davide Giuseppe Farella]

( here it is the lib on jCenter https://mvnrepository.com/artifact/studio.forface.easygradle/dsl )

[no]

your example/sample is a composite build, whereas in Nicola's project it is a regular part of the build.

[Davide Giuseppe Farella]

Before the publishing was included there, now I'm separating and shipping as regular plugin, regarding the publishing side

[Davide Giuseppe Farella]

your example/sample is a composite build, whereas in Nicola's project it is a regular part of the build.

I did in that way just because I wanted to showcase also how to use dsl , by including it in its buildSrc.
But I think that's not a big issues, as I would use the plugin in a completely different project 🙂

[Davide Giuseppe Farella]

FYI: replaced the jar with the version from Bintray and it works flawlessly 🙂 Thank you
