     If `--retry-once-with-cleanup=true`, then in each failed directory the cached modules and providers from the `.terraform` directory will be deleted, before retrying once more. To avoid unnecessary deletion of this directory, the cleanup and retry will only happen if Terraform produces any of the following error messages:
 
-    * Missing or corrupted provider plugins
-    * Module source has changed
-    * Module version requirements have changed
-    * Module not installed

     **Warning:** When using `--retry-once-with-cleanup=true`, problematic `.terraform/modules/` and `.terraform/providers/` directories will be recursively deleted without prompting for consent. Other files and directories will not be affected, such as the `.terraform/environment` file.
