Expected Behavior

terraform show should output the plan as expected

Actual Behavior

terraform show fails to load plugin schema although terraform init works as expected in offline mode as well as plan, we have a working plan output but need it in json format. We have no internet access from where we execute terraform.

Steps to Reproduce

1. configure terraform to work in "offline mode" using .terraformrc and point it to private repository (we're using nexus).
2. terraform init
3. terraform plan >
4. terraform show -json
