Moving from artifactory_group to platform_group causes some issue with member list

[stefan-sesser]

Describe the bug
For all artifactory_group resources in our terraform repo, I get a deprecation warning:
This resource is deprecated. Use 'platform_group' resource in the JFrog Platform provider instead.
After re-importing the group as platform_group and doing another terraform plan I see the following changes:

  platform_group.test_group will be updated in-place
  ~ resource "platform_group" "test_group" {
    - members          = [
      - "test-user",
      ] -> null
      name             = "test-group"
   ~ realm            = "internal" -> (known after apply)
   + realm_attributes = (known after apply)
      # (2 unchanged attributes hidden)
   }

According to JFrog Artifactory Terraform recommendation, I should use the artifactory_user for managing the user-group relationship.
https://registry.terraform.io/providers/jfrog/artifactory/latest/docs/guides/user_group

How can I solve this situation?

I already thought of moving the user-group relationship to platform_groups. Unfortunately, if I leave the groups argument empty, I will not get the default readers group attached to the user.

Requirements for and issue

• A description of the bug
• A fully functioning terraform snippet that can be copy&pasted (no outside files or ENV vars unless that's part of the issue). If this is not supplied, this issue will likely be closed without any effort expended.

resource "platform_group" "test_group" {
  name             = "test-group"
  admin_privileges = false
  auto_join        = false
}

resource "artifactory_user" "testuser" {
  admin                      = true
  disable_ui_access          = false
  email                      = "[email protected]"
  internal_password_disabled = true
  name                       = "test-user"
  profile_updatable          = true

  groups = [
    "readers",
    platform_group.test_group.name
  ]
}

• Your version of artifactory (you can curl it at $host/artifactory/api/system/version

• Your version of terraform
  Terraform v1.9.8
• Your version of terraform provider

artifactory = {
      source  = "jfrog/artifactory"
      version = "12.5.1"
    }
    platform = {
      source  = "jfrog/platform"
      version = "1.18.2"
    }

@stefan-sesser Thanks for the report. I think the solution is to implement separate resources for the user-group relationship in #169.

@alexhung Yey, this would be awesome. Thanks for your fast response.
