Terraform Version

terraform 0.13.2

Affected Resource(s)

• artifactory_remote_repository

Probably all resources that have string fields that it is valid to be the empty string.

Terraform Configuration Files

Using gocenter.io as a remote for the purposes of this example

Initial state

resource "artifactory_remote_repository" "someremote" {
  url             = "https://gocenter.io"
  key             = "gocenter"
  package_type    = "go"
  repo_layout_ref = "go-default"
  proxy           = "someproxy"
}

Second apply

resource "artifactory_remote_repository" "someremote" {
  url             = "https://gocenter.io"
  key             = "gocenter"
  package_type    = "go"
  repo_layout_ref = "go-default"
  proxy           = ""
}

Expected Behavior

Proxy should have been removed with a change of

proxy "someproxy" -> ""

Actual Behavior

Proxy field not passed to the API, as it got reduced to null

proxy "someproxy" => null

This retains the value "someproxy" in the remote.

Steps to Reproduce

This affects any string field in which changing the field to "" in the API would be a valid change.

1. terraform apply with initial state
2. terraform apply after changing a string field to ""

Possible fix

At https://github.com/atlassian/terraform-provider-artifactory/blob/master/pkg/artifactory/util.go#L15
d.GetOk(key) should perhaps be d.GetOkExists(key) so that empty strings are not treated as null
