How do I change the name of the war file when using Kotlin DSL?

I’m using Gradle 6.0.1 with Kotlin DSL. My build script uses the war plugin. How can I change the name of the war file built?

An older answer to a similar question (see uses Groovy. I’m not sure how to achieve the same effect when using Kotlin.

Tried the following, but it did not work.

war {
    archiveFileName = "something.war"


You’ll need to be a bit more explicit in Kotlin. Get war from tasks and use the set method since archiveFileName is a Property<String>, not just a String.

tasks.war {

java.sourceCompatibility = JavaVersion.VERSION_11

tasks.war {
