How to overwrite a task?

[xeruf]

I can't find any documentation or sample on how to overwrite a task.

I've tried it a little bit and came to this solution:

tasks("copy") {
  doLast {
    println("HelloWorld")
  }
}

tasks.replace("copy").doLast {
   println("Not Hello World")
}

This will print Not Hello World.

We have to use the TaskContainer#replace since there is no extension function yet in the Kotlin DSL:
https://github.com/gradle/kotlin-dsl/blob/6565d94a752d475b01b0afecdd4a3eb8b2155ce6/provider/src/main/kotlin/org/gradle/kotlin/dsl/ProjectExtensions.kt#L110-L140

I think we should add the extension functions to the ProjectExtensions class :)

Would be good to add a sample for this

[StefMa]

As long as it isn't really supported it don't need a sample. Additionally not everything needs a sample IMO.

Closing as answered

I don't think that it should be closed. Better to keep it open to remind us to to add the extension function...

The Gradle API provides TaskContainer#replace.

// TaskContainer.java
Task replace(String name);
<T extends Task> T replace(String name, Class<T> type);

There's no need for an extension on the Gradle Kotlin DSL side to make this usable.

But as it stands now, I can't find a way to override a task within a tasks block, but have to use a separate tasks.replace call, which is inconvenient

Good point @Xerus2000!
tasks {} block receiver is a NamedDomainObjectContainer<Task>.
The TaskContainer methods aren't available in there.

I opened #716 to account for the more general issue.

Any news on this?
