[janvladimirmostert]

in a root build.gradle.kts you can set the version for all plugins:

plugins {

	val kotlinVersion = "1.4.21"
	val shadowVersion = "6.0.0"

	kotlin("multiplatform").version(kotlinVersion).apply(false)
	kotlin("plugin.serialization").version(kotlinVersion).apply(false)
	id("com.github.johnrengelman.shadow").version(shadowVersion).apply(false)

}

is there a way to do it with dependencies as well?
I've tried adding a dependency block with a constraint{...}, but the IDE doesn't allow me to add an implementation(...) inside such a constraint block

Isn’t this what you’re looking for? https://docs.gradle.org/current/userguide/java_platform_plugin.html#sec:java_platform_consumption

[jbnizet]

Note that you can set the versions of plugins that way, too: https://docs.gradle.org/current/userguide/plugins.html#sec:plugin_version_management

do i need a specific version of gradle to make use of dependency constraints ?

[janvladimirmostert]

let me try upgrade my gradle, I'm on 6.5

You need to use it inside a specific project, where the java-platform plugin is applied. And then, in “regular” projects, you declare dependencies on this specific platform project to benefit from its declared versions.

[jbnizet]

i.e. in a “platform” subproject, you would have

plugins {
    `java-platform`
}

repositories {
    mavenCentral()
}

dependencies {
    constraints {
        api("foo:bar:1.2.3")
    }
}

[jbnizet]

And in other subprojects, you would have

dependencies {
    implementation(platform(project(":platform")))

    implementation("foo:bar")
}

Yep, platform is the way to go for now

In 7.0 we will probably get versios catalog api and finally it would be concise, simple way for version declaration

thank you, I'll take the platform(project( thing for a test drive tonight!
