+
+The resource for managing Code Repository Index for Gemini Code Assist.
+
+~> **Warning:** This resource is in beta, and should be used with the terraform-provider-google-beta provider.
+See [Provider Versions](https://terraform.io/docs/providers/google/guides/provider_versions.html) for more details on beta resources.

+
+
+```hcl
+resource "google_gemini_code_repository_index" "example" {
+  provider = google-beta
+  location = "us-central1"
+  code_repository_index_id = ""
+  kms_key = "projects/projectExample/locations/locationExample/keyRings/keyRingExample/cryptoKeys/cryptoKeyExample"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+
+* `location` -
+  (Required)
+  The location of the Code Repository Index, for example `us-central1`.
+
+* `code_repository_index_id` -
+  (Required)
+  Required. Id of the Code Repository Index.
+
+
+- - -
+
+

+
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following computed attributes are exported:

+* `id` - an identifier for the resource with format `projects/{{project}}/locations/{{location}}/codeRepositoryIndexes/{{code_repository_index_id}}`
+
+* `update_time` -
+  Output only. Update time stamp.
+
+* `state` -
+  Output only. Code Repository Index instance State.
+  Possible values:
+  STATE_UNSPECIFIED
+  CREATING
+  ACTIVE
+  DELETING
+  SUSPENDED
+
+* `name` -
+  Immutable. Identifier. Name of Code Repository Index.
+
+* `create_time` -
+  Output only. Create time stamp.
+
+* `terraform_labels` -
+  The combination of labels configured directly on the resource
+   and default labels configured on the provider.

+
+## Import
+
+
+CodeRepositoryIndex can be imported using any of these accepted formats:
+
+* `projects/{{project}}/locations/{{location}}/codeRepositoryIndexes/{{code_repository_index_id}}`
+* `{{project}}/{{location}}/{{code_repository_index_id}}`
+* `{{location}}/{{code_repository_index_id}}`
+
+
+In Terraform v1.5.0 and later, use an [`import` block](https://developer.hashicorp.com/terraform/language/import) to import CodeRepositoryIndex using one of the formats above. For example:
+
+```tf
+import {
+  id = "projects/{{project}}/locations/{{location}}/codeRepositoryIndexes/{{code_repository_index_id}}"
+  to = google_gemini_code_repository_index.default
+}
+```
+
+When using the [`terraform import` command](https://developer.hashicorp.com/terraform/cli/commands/import), CodeRepositoryIndex can be imported using one of the formats above. For example:
+
+```
+$ terraform import google_gemini_code_repository_index.default projects/{{project}}/locations/{{location}}/codeRepositoryIndexes/{{code_repository_index_id}}
+$ terraform import google_gemini_code_repository_index.default {{project}}/{{location}}/{{code_repository_index_id}}
+$ terraform import google_gemini_code_repository_index.default {{location}}/{{code_repository_index_id}}
+```
