How to rewrite Groovy gradle task to Kotlin gradle scripts

Question

I have these two gradle tasks written in groovy and I can't find a proper way how to rewrite them to Kotlin:

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}


task clearAppCache(type: Exec) {
    def clearDataCommand = ['adb', 'shell', 'pm', 'clear', 'io.hruska.pocketplay']
    commandLine clearDataCommand
}

I am especially not sure about how to replace the "commandLine" method and how to add a "type:Exec" argument to task.

Answer 1

I believe the following should do the trick:

tasks {

    // will need to import KotlinCompile or use the fully qualified name
    withType<KotlinCompile> {
        kotlinOptions.jvmTarget = "1.8"
    }

    register<Exec>("clearAppCache") {
        commandLine = listOf("adb", "shell", "pm", "clear", "io.hrushka.pocketplay")
    }

}
