I'm getting an error running a task defined in my gradle plugin:

Execution failed for task ':setupMetadata'.
> Extension of type 'KPyExtension' does not exist. Currently registered extension types: [ExtraPropertiesExtension]

but in my plugin I have

// fun Project.setupExtensions(), called first
extensions.create<KPyExtension>("kpy")  // register extension

// fun Project.setupTasks(), called later
task<Task>("setupMetadata") {
    actions.add {
        val target = kotlinExtension.targets.first { it is KotlinNativeTarget } as KotlinNativeTarget
        val ext = the<KPyExtension>()  // error here I'm assuming
        // task action
    }
}

I am able to use the kpy keyword in my build.gradle.kts file to configure it and in other parts of the plugin it works fine

probably it's looking for the extension on the wrong object, try project.the<KPyExtension>()

It is, task is extension aware, so you are looking in the task extensions instead of in the project extensions. Btw. You shouldn't use actions.add but doLast, and you are using eager task(...) method, not leveraging task configuration avoidance with tasks.register

[ephemient]

or write a task class instead of an ad-hoc one like this, it's easy and will allow for custom properties to be configured by the extension, caching, etc.

Yes, definitely. But then still use register to create it 🙂
