The previous changes removing support for using the trailing positional argument as a working directory missed a spot in the
apply
/destroy
command implementation. We still support this argument for applying a saved plan:However, if you pass a positional path which doesn't "look like" a plan (for example, the path to a configuration directory), Terraform would silently ignore it and continue.
This commit fixes that by adding an error message if the user specifies a path which the plan loader rejects as not "looking like" a plan. This message includes a reference to the
-chdir
flag as a pointer about what to do next.We also rearrange the error message when calling
terraform destroy
with a plan file argument, and add test coverage for the above. While we're here, update the destroy tests to copy the fixture directory, chdir, and defer cleanup.
