Deprecated google.account_file still necessary for google_compute_project_metadata?

[beldur]

After updating to the new Terraform Version 0.6.7 and replacing the account_file property with credentials, I get the following warning:

provider.google.account_file
Enter a value: 

There are warnings and/or errors related to your configuration. Please fix these before continuing.

Warnings:
* provider.google: "account_file": [DEPRECATED] Use the credentials field instead

I tracked it down to the google_compute_project_metadata resource. The following code is my tf file. And as soon as the google_compute_project_metadata is commented out, the warning disappears.

provider "google" {
    credentials = "${file("path/to/file.json")}"
    project = "myproject"
    region = "europe-west1"
}

resource "google_compute_project_metadata" "default" {
    metadata { foo = "bar" }
}

This is also affecting me, I've not got the metadata resource like @beldur, I see it a module with just google_compute_firewall resources. This appears to be mentioned in #3901 as a potential problem, which appears it is.

I'm having the same problem but I'm using it with google_dns_managed_zone and google_dns_record_set resources.

Very odd, I'll look into this soon.

I have seen this bug as well. To get around it, I just keep account_file in there set to nothing:

provider "google" {
    account_file = ""
    credentials = "${file("path/to/file.json")}"
    project = "myproject"
    region = "europe-west1"
}

Still throws a warning, but it prevents the Enter a value: prompt, and allows Atlas to keep working.

[lwander]

Both credentials and account file are marked as optional here. @phinze, @jen20, any idea why Terraform would prompt you to enter an optional value?

[phinze]

@coreone Atlas should be setting -input=false, were you still seeing prompts there?

@lwander hm, I'm not sure offhand. Will have to dig in and get back to you.

[phinze]

Yep looks like providers are dumber about Input() than I thought.

Enhancements to input are being discussed over in https://github.com/hashicorp/terraform/issues/1255, but for this I'll just PR to always skip input on Deprecated fields.
