Hello community 👋 I am looking for the way to add dependency to the existing configuration. The brief steps are: 1. Make a network call to get the json, save it to file expose it as task output. The task named as

LoadCommunityNativeConfig

. 2. Wire task output to the project relying on

org.gradle.api.provider.Provider

. The problem is that the

LoadCommunityNativeConfig

is not executed when its output accessed. As far as I understand, I am missing a proper wiring of

LoadCommunityNativeConfig

to the existing tasks. The Gradle runtime throws

Querying the mapped value of flatmap(provider(task 'loadCommunityNativeConfig', class LoadCommunityNativeConfig)) before task ':app:loadCommunityNativeConfig' has completed is not supported

Below 2 approaches I’ve tried to add the dependency. Snippet 1

project.dependencies.addProvider("implementation", loadCommunityNativeConfig.flatMap { it.outArtifact }.map {
    // maps json file to data class NativeConfig
	val nativeConfig: NativeConfig = it.asFile.toNativeConfig()
	val isEnabled = nativeConfig.facebookConfig.isNoOp
	if (isEnabled) {
	  "com.facebook.android:facebook-core:17.0.1"
	} else {
	  "javax.inject:javax.inject:1"
	}
})

Snippet 2

val implementation = project.configurations.named("implementation")
val dependencies = project.dependencies

implementation.configure {
    val container = this
    container.dependencies.addLater(
        loadCommunityNativeConfig.flatMap { it.outArtifact }.map {
            val nativeConfig = it.asFile.toNativeConfig()
            val isEnabled = nativeConfig.facebookConfig.isNoOp
            if (isEnabled) {
                dependencies.create("com.facebook.android:facebook-core:17.0.1")
            } else {
                dependencies.create("javax.inject:javax.inject:1")
            }
        }
    )
}

In addition, I’ve tried to combine ☝️ both approaches with this snippet.

project.artifacts.add("implementation", loadCommunityNativeConfig.flatMap { it.outArtifact }) {
            builtBy(loadCommunityNativeConfig)
        }

I would appreciate any feedback or guidance in the right direction 🙇

Yeah, well, you most probably cannot do the network call in a task's execution phase then, unless maybe that specific configuration is only resolved at execution time. Which for example then also means no configuration cache, ever.

Just make the network call in a provider there directly.

Worked out.
