I need to inject the

ExtensionContainer

into an extension (to manipulate another extension). How can I do this?

> Unable to determine constructor argument #2: missing parameter of type ExtensionContainer, or no service of type ExtensionContainer.

abstract class ArtifactoryPublisherExtension @Inject constructor(
    layout: ProjectLayout,
    // neither work
    // extensions: ExtensionContainer
    // publishingExtension: org.gradle.api.publish.PublishingExtension
) {

Only services (like ProjectLayout) are automatically injectable, and for additional args you'll have to pass them in manually when creating the extension (or when using

ObjectFactory.newInstance()

)

project.extensions.create(
  "artifactoryPublisher",
  ArtifactoryPublisherExtension::class, 
  project.extensions, // add additional arg
)

that’s a bummer, but thank you!

Fwiw, there's no the extension container, there's one extension container per

ExtensionAware

, and many many objects in Gradle are extension aware (all tasks, many extensions themselves, etc. anything created through

ObjectFactory

or similar actually IIUC)
