Migrating from old apply plugin to plugins block

Help/Discuss

Hi!

I use the plugin which has an official application way as follows:

buildscript {
	val korgePluginVersion: String by project

	repositories {
		mavenLocal()
		mavenCentral()
		google()
		maven { url = uri("https://plugins.gradle.org/m2/") }
	}
	dependencies {
		classpath("com.soywiz.korlibs.korge.plugins:korge-gradle-plugin:$korgePluginVersion")
	}
}

apply<KorgeGradlePlugin>()

Its artifact is com.soywiz.korlibs.korge.plugins:korge-gradle-plugin:2.1.1.4.

I would like to use a modern way of plugin application. What I’ve come up is as follows:

pluginManagement {
    repositories {
        mavenLocal()
        mavenCentral()
        google()
        maven("https://plugins.gradle.org/m2/")
    }

    val korgePluginVersion: String by settings

    resolutionStrategy {
        eachPlugin {
            if (requested.id.id == "com.soywiz.korge") {
                useModule("com.soywiz.korlibs.korge.plugins:korge-gradle-plugin:$korgePluginVersion")
            }
        }
    }

    plugins {
        id("com.soywiz.korge") apply false
    }
}

After it, I can easily apply it as plugins { id("com.soywiz.korge") } in the required modules.

However, I don’t like this way since it seems more natural to me to specify version in the plugins block, like this:

```kt
pluginManagement {
    repositories {
        mavenLocal()
        mavenCentral()
        google()
        maven("https://plugins.gradle.org/m2/")
    }

    val korgePluginVersion: String by settings

    resolutionStrategy {
        eachPlugin {
            if (requested.id.id == "com.soywiz.korge") {
                useModule("com.soywiz.korlibs.korge.plugins:korge-gradle-plugin")
            }
        }
    }

    plugins {
        id("com.soywiz.korge") version korgePluginVersion apply false
    }
}

Here I have an exception: Invalid format: 'com.soywiz.korlibs.korge.plugins:korge-gradle-plugin'. Group, name and version cannot be empty. Correct example: 'org.gradle:gradle-core:1.0'.

Also, I’m not sure whether I need resolutionStrategy at all… Maybe I just need to specify a different plugin ID and everything starts working itself…

So could somebody advise what’s a proper way to migrate from apply plugin to plugins block in my case?
