What is a replacement for meta runners in TeamCity Kotlin DSL? - kotlin

Question

Apparently there's no support for metarunners generation in TeamCity Kotlin DSL. The files remain in plain XML.
How do I replace it using available DSL features? Say I'd like to do this:
steps {
step {
type = "mymetarunner" // compound meta-runner step
}
}
How do I define mymetarunner using Kotlin?

Answer 1

At the moment (TeamCity 2017.2), there is no way to define metarunners using Kotlin DSL.
Update
If having a real metarunner is not required, the solution is a small exercise in Kotlin DSL
Define a container class for settings you need for "metarunner"
class MyConfigClass {
var name = "Default Name"
var goals = "build"
var tasks = "build test"
var someUnusedProperty = 0
}
Define an extension function for steps block
fun BuildSteps.myMetaRunner(config: MyConfigClass.() -> Unit) {
val actualConfig = MyConfigClass() // new config instance
actualConfig.config() // apply closure to fill the config
// use the config to create actual steps
maven {
name = actualConfig.name
goals = actualConfig.goals
}
ant {
name = actualConfig.tasks
}
}
Use the extension function wherever you need
object A_Build : BuildType({
uuid = ...
steps {
myMetaRunner {
name = "This name will be used by maven step"
goals = "build whatever_goal"
tasks = "more ant tasks"
}
}
})
Bingo!
