Summary

It is not clear from the output of tflint which modules are missing a required_version for terraform. The warning just says on line 0: (source code not available) which is not helpful for finding the issue.

Command

tflint --recursive

Terraform Configuration

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.49"
    }
  }
}

data "aws_availability_zones" "available" {}

TFLint Configuration

tflint {
  required_version = "~> 0.51"
}

plugin "terraform" {
  enabled = true
  preset  = "recommended"
}

plugin "aws" {
    enabled = true
    version = "0.31.0"
    source  = "github.com/terraform-linters/tflint-ruleset-aws"
}

I agree that there is room for improvement in the current output, but be aware that this is a rule that reports "missing" required declarations, so you may not always get a valid range. For example, we may also need to report this issue for empty directories.

Yeah, thank you. That makes sense. I get why we'd see (source code not available) for a "missing" report, but an indication of the file or directory would at least make the warning actionable.
