how do I fix this, it doesn’t compile

tasks {
    val dependsOnModules: Task.() -> Unit = {
            gradle.includedBuilds.forEach { dependsOn(it.task(":${this.name}")) }
    }
    "build" dependsOnModules
    "clean" dependsOnModules
    "wrapper" dependsOnModules
}

wrap the method calls with

()

What you exactly want to do? This is incorrect Kotlin syntax. Probably you just should add curly brackets and invoke this lambda:

"build" { dependsOnModules() }

@gildor

"build"(dependsOnModules)

appears to work, I had the body of that val copied into all 3 and I was trying to deduplicate it
