How to add arguments to a org.gradle.api.Action? - gradle

Question

I'm writing a custom Gradle plugin that registers an extension and uses Actions for configuring it so you can use it like
myExtension {
info {
someConfig("a") {
// config for someConfig["a"]
}
someConfig("b") {
// config for someConfig["b"]
}
}
}
Based on how much someConfig you define, the plugin created new Gradle tasks dynamically. I've seen some scenarios in which it'd useful to configure all someConfig with the same values, so instead of writing
myExtension {
info {
someConfig("a") {
someValue = x
}
someConfig("b") {
someValue = x
}
}
}
I was thinking in providing something like
myExtension {
info {
someConfig("a")
someConfig("b")
allConfigs { configName ->
someValue = x
}
}
}
When trying to code it, I've used an objectFactory for creating instances of Action so I can configure the extension values
val allMyConfigs = mutableMapOf<String, SomeConfig>()
fun someConfig(configName: String, init: Action<in EnvironmentInfo>) {
val myConfig = allMyConfigs.computeIfAbsent(env) {
objectFactory.newInstance(SomeConfig::class.java, env)
}
init.execute(environmentInfo)
}
but since Action is a (SomeConfig) -> Unit (i.e. a function receiving a SomeConfig instance) I'm unable to pass the config name (an String) as param
Is there a way to create an Action, so it's compatible with both build.gradle and build.gradle.kts files, that receives an extra parameter and maintain the SomeConfig as delegate?
