Data Source and Import State

Add a data source and import state support to the existing example resource in the HashiCorp scaffold.

Setup

git clone https://github.com/hashicorp/terraform-provider-scaffolding-framework.git .
git checkout 3f9b7d20f49724d61ffaa28f5812c347b6a3e4a1
go mod tidy

Task

Part 1: Add a data source

Create an example_data_source that reads an item by its id attribute. The scaffold already has a data source file - modify it to:

• Accept id as a Required String attribute
• Return name as a Computed String attribute (looked up by ID)
• Properly handle the case where the item is not found (add an error diagnostic)
• Check diagnostics after all Config.Get and State.Set calls

Part 2: Add import state to the resource

Modify the existing example_resource to support Terraform import:

• Implement the ResourceWithImportState interface
• Use resource.ImportStatePassthroughID to import by the id attribute
• Add an import test step to the existing test file using ImportState: true and ImportStateVerify: true

Part 3: Write acceptance tests

• Write an acceptance test for the data source that creates a resource first, then reads it via the data source using a reference to the resource's id
• Add an import test step to the resource test

Ensure the project builds with go build ./....
