Mapping Extension Properties to Tasks in kotlin-dsl. I am attempting to implement an extension property as the default for a task property by following the example in kotlin-dsl/samples/provider-properties. Mostly working -- in a groovy build script It 'works' however in a kotlin build script the property ( Property<String>) seems directly exposed -- I need to write
property.set("value")
instead of
property = "value"

Example:
In extension Object:
val bucket = project.objects.property<String>()

In Task:
open class CreatePackageTask : AbstractExecTask<CreatePackageTask>(CreatePackageTask::class.java) {

...
@get:Input
val bucket = project.objects.property<String>()
....
@TaskAction
override fun exec() : Unit {
val bucket = bucket.get()
....

Registering Task (in plugin.gradle.kts)

tasks {
register("createPackage", CreatePackageTask::class){
group = "cloud"
bucket.set(cloud.bucket)

...

So far so good ... but in the calling buildscript:
groovy: (build.gradle)

cloud {
bucket = "bucket" // 'just works'

kotlin: (build.gradle.kts)

cloud {
bucket = "bucket" // ERROR val cannot be reassigned , ERROR Inferred type is String but expected type is Property<String>

... this works ->
bucket.set("bucket")

-->

What is the correct way to get the last case to work ?
Thinking of instead a 'var' and overriding 'set(value: String)'

This worked: Adding ->
public fun setBucket(_bucket : String) { bucket.set(_bucket) }

Seems pretty hacky .. (and would need be done for all properties). Any recomendations ?
