Previously we were using the experimental HCL 2 repository, but now we'll shift over to the v2 import path within the main HCL repository as part of actually releasing HCL 2.0 as stable. This is a mechanical search/replace to the new import paths. It also switches to the v2.0.0 release of HCL, which includes some new code that Terraform didn't previously have but should not change any behavior that matters for Terraform's purposes. For the moment the experimental HCL2 repository is still an indirect dependency via terraform-config-inspect, so it remains in our go.sum and vendor directories for the moment. Because terraform-config-inspect uses a much smaller subset of the HCL2 functionality, this does still manage to prune the vendor directory a little. A subsequent release of terraform-config-inspect should allow us to completely remove that old repository in a future commit.

`2 problems:
|
|
|
|
- Missing resource instance key: Because aws_instance.count has "count" set, its attributes must be accessed on specific instances.
|
|
|
|
For example, to correlate with indices of a referring resource, use:
|
|
aws_instance.count[count.index]
|
|
- Unsupported attribute: This object has no argument, nested block, or exported attribute named "foo".`,
