You may encounter a files synchronization issue after manually deleting the files from your Databricks Asset Bundle's workspace (e.g. /Workspace/Users/your_user/.bundle/your_project/dev/files). The issue consists of not uploading all the files to the workspace directory because DAB won't upload the files that haven't changed. To resolve this problem you can run the following command to update the modification time of the underlying files: find . -type f -exec touch {} +.
