How can I run Kotlin-Script (*.kts) filles from within Gradle?

How can I run Kotlin-Script (*.kts) filles from within Gradle?

From the command line, I can call:
kotlinc -script foo.kts

How can I do this from gradle (build.gradle)?


(Rodrigo B. de Oliveira) #2

Hello, Richard.

If I understand you correctly, you want to execute an arbitrary Kotlin script from a Gradle build script, right?

If that’s the case, a somewhat straightforward way would be to drive kotlinc (org.jetbrains.kotlin.cli.jvm.K2JVMCompiler) directly
as exemplified by this gist: https://gist.github.com/bamboo/f29e738c2a17a36e87c814b7452afe31

A simpler, more performant and more manageable solution would be to use a Kotlin build script (build.gradle.kts) and express the intent of each separate script as one or more tasks.

// build.gradle.kts
//
// Execute Kotlin task with
//
//    gradle -b build.gradle.kts -q foo
//

task("foo") {
  group = "My"
  description = "Foos away"
  doLast {
    println("Hello from foo task")
  }
}

Let me know if that answers your question.

Cheers,
Rodrigo

Hello Rodrigo,

I tried to run the build.gradle.kts file from the gist, but got many errors (see below). What am I doing wrong?

Thanks.

(Rodrigo B. de Oliveira) #5

I’m sorry for the confusion, Richard. The build script file in the gist should be saved as build.gradle (not build.gradle.kts) because it’s written in Groovy.

The Kotlin equivalent of that whole gist was presented inline instead of a gist because it was a single small script.
