[Bug]: Updating YAML content of the 'buildspec' argument for the 'aws_codebuild_project' resource does not update the buildspec document in AWS

[clarkhathawayaltview]

Terraform Core Version

1.9.7

AWS Provider Version

5.72.0

Affected Resource(s)

aws_codebuild_project

Expected Behavior

When using the built-in yamlencode function to provide the YAML document for the CodeBuild project buildspec, updating the content of this document in the configuration should update the buildspec in AWS after a standard plan & apply.

Actual Behavior

The YAML document for the buildspec in AWS is not updated after a standard plan & apply.

Terraform Configuration Files

variable codebuild-service-role-arn {
  type = string
}

variable codeartifact-repository {
  type = string
}

variable codeartifact-domain {
  type = string
}

variable codeartifact-domain-owner {
  type = string
}

variable codebuild-environment-image-uri {
  type = string
}

resource aws_codebuild_project _ {
  name = "..."
  service_role = var.codebuild-service-role-arn

  source {
    buildspec = yamlencode({
      version = "0.2"

      phases = {
        build = {
          commands = [
            "command1",
            "command2"
          ]
        }
      }
    })
    type = "BITBUCKET"
    location = "..."
  }

  environment {
    compute_type = "BUILD_GENERAL1_SMALL"
    image        = var.codebuild-environment-image-uri
    image_pull_credentials_type = "SERVICE_ROLE"
    type         = "LINUX_CONTAINER"
  }

  artifacts {
    type = "NO_ARTIFACTS"
  }
}

Steps to Reproduce

1. Replace the redacted content of the configuration file above with usable values
2. Create the resource with a standard plan & apply
3. Change the commands field of the buildspec, perhaps adding or removing commands but any change here will suffice.
4. Run another standard plan & apply
5. Observe that the YAML document in AWS remains unchanged for this resource
