Creating xray_watch resource with ant_filter and empty "exclude_pattern" results in recreating the reource on every run

[jan-huso]

I'm creating an xray_watch resource and define an include_pattern in the ant_filter. The exclude_pattern should be empty so I use [].
The resource is created succesfully but on every new run tf wants to recreate the watch_resource because the exclude_pattern is "missing".

Tested on TF 1.9.5 and xray 2.11

TF source code:

resource "xray_watch" "repository-ant-filter" {
  name        = "repository-watch-test"
  description = "Watch a single repo or a list of repositories, using ant pattern"
  active      = false
  project_key = "lzt2"

  watch_resource {
    type = "all-builds"
    # bin_mgr_id = "default"
    # name       = "your-repository-name"
    # repo_type  = "local"

    ant_filter {
      exclude_patterns = []
      include_patterns = ["**/*.js"]
    }
  }

TF plan after the resource is already created

Terraform will perform the following actions:

  # xray_watch.repository-ant-filter will be updated in-place
  ~ resource "xray_watch" "repository-ant-filter" {
        name        = "repository-watch-test"
        # (3 unchanged attributes hidden)

      - watch_resource {
          - bin_mgr_id = "default" -> null
          - type       = "all-builds" -> null

          - ant_filter {
              - include_patterns = [
                  - "**/*.js",
                ] -> null
            }
        }
      + watch_resource {
          + bin_mgr_id = "default"
          + type       = "all-builds"

          + ant_filter {
              + exclude_patterns = []
              + include_patterns = [
                  + "**/*.js",
                ]
            }
        }
    }

@jan-huso If you wish to have an empty patterns, have you tried omitting the attribute completely?

[jan-huso]

@alexhung yes, but I get an error with terraform, that the attribute is required

[alexhung]

@jan-huso Thanks! I'll investigate.

[alexhung]

@jan-huso Using the following TF configuration, I am able to create the policy and watch without the exclude_patterns attribute:

terraform {
  required_providers {
    xray = {
      source  = "jfrog/xray"
      version = "2.11.0"
    }
  }
}

resource "xray_security_policy" "security" {
  name        = "test-policy"
  description = "Security policy description"
  type        = "security"
  rule {
    name     = "rule-name-severity"
    priority = 1
    criteria {
      min_severity = "High"
    }

    actions {
      mails    = ["[email protected]"]
      block_download {
        unscanned = true
        active    = true
      }
      block_release_bundle_distribution  = true
      fail_build                         = true
      notify_watch_recipients            = true
      notify_deployer                    = true
      create_ticket_enabled              = false
      build_failure_grace_period_in_days = 5
    }
  }
}

resource "xray_watch" "test-watch" {
  name = "test-watch"
  active = true

  watch_resource {
    type       	= "all-builds"
    bin_mgr_id  = "default"

    ant_filter {
      include_patterns = ["**/*.js"]
    }
  }

  assigned_policy {
    name 	= xray_security_policy.security.name
    type 	= "security"
  }

  watch_recipients = [
    "[email protected]",
  ]
}

Running this with Terraform 1.9.5, provider 2.11.0, Xray 3.014.10:

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed.

@jan-huso I repeated the same configuration but with a project_key set and result is same. I am able to create the watch resource without the exclude_patterns attribute.

[jan-huso]

@alexhung thx for the example, I will try to reproduce it on my side :)

[jan-huso]

@alexhung i tested your code and it worked on my side as well. I did not declare my variable as optional. Thx for the help and sorry for the wrong bug report! :)
