Hello. I'm sorry fo stupid question, but...
How in gradle kotlin dsl I can add task for copy file from one location to other?
(Unfortunatly, I can't understand this example https://github.com/gradle/kotlin-dsl/blob/master/samples/copy/build.gradle.kts)

[Torbilicious]

What about the given sample don't you understand?

[Torbilicious]

a very simple example would be

tasks.create<Copy>("copyStuff") {
    from("/some/source")
    into("/some/destination")
}

Is that what you are looking for?

[Torbilicious]

or in the syntax from the example:

tasks {
    register("copyStuff", Copy::class) {
        from("/some/source")
        into("/some/destination")
    }
}

register<Copy> also will work on Gradle 5
Also register is lazy API, create is eager

@Torbilicious @gildor
Both variants does not work for me.

tasks{
    create<Copy>("copyStuff") {
        from(".")
        into("out/production")
        include("properties/monportalCache.properties")
    }
    register("copyStuff", Copy::class) {
        from(".")
        into("out/production")
        include("properties/monportalCache.properties")
    }
    copy {
        from(".")
        into("out/production")
        include("properties/monportalCache.properties")
    }
}

First and second does not work. Third is only working variant.

Where I'm wrong?

@rjhdby All 3 work for me with Gradle 5. Did you tried to build it? Maybe just some IDE issue. Also, do you try to use those APIs in build.gradle.kts or in some custom plugin?

[gildor]

Also 3rd is actually not a task (so can be moved out off tasks block), this is project’s method, part of project evaluation lifecycle
https://docs.gradle.org/current/dsl/org.gradle.api.Project.html#org.gradle.api.Project:copy(org.gradle.api.Action)

@gildor
In fact, if I use copy method then inside into directory I see properties/blabla, if I use register or create - I don't see anything

[gildor]

@rjhdby Do you run task copyStuff?

[gildor]

because project.copy invokes by default, tasks are not and you have to run them explicitly or add as dependency to some other task in a project graph

[gildor]

Just checked, if I run copyStuff task I see output

[gildor]

Also, side point to be clear and point again that there is no difference in syntax between create and register task builders, both support register("copyStuff", Copy::class) and register<Copy>("copyStuff") syntax, just second one is more idiomatic and Kotlin friendly IMO, difference only about eager/lazy task creation

@gildor You are right. I do not execute copy task at all. 🤦‍♂️
Thank you!
