When creating an extension on a task, Gradle fails to inject services (ObjectFactory, ProviderFactory, etc).

Expected Behavior

When adding extensions to the project or objects created using ObjectFactory.newInstance, services are correctly injected into the extension's constructor. This does not work for extensions created on tasks, but probably should.

Current Behavior

Creation of the task extension fails with missing parameter of type <service>, or no service of type <service>.

Steps to Reproduce

class MyExt {
    Property<String> myProp
    @javax.inject.Inject
    MyExt( ObjectFactory objectFactory, String target ) {
        println "target: ${target}, service: ${objectFactory}"
        myProp = objectFactory.property( String )
        myProp.set( target )
    }
}
interface MyType {
}

[
    project: project,
    object: objects.newInstance( MyType ),
    task: tasks.create( 'myTask' )
].each { t, o ->
    o.extensions.create( 'myExt', MyExt, t )
    println o.myExt.myProp.get()
}
