Summary

Changes

Previously, when a user specified a custom build path using the --o/--output parameter, the entire output_path was cleaned before building the add-on. This could result in unintended loss of existing files in that directory.

Therefore, added a new flag--overwrite for the build command. Now, we only attempt to clean the output_path/<ta_name> directory if the --overwrite flag is provided. If the --overwrite flag is not passed and the output_path/<ta_name> directory already exists, the build will fail and prompt the user to either pass the --overwrite flag or choose a different output path.

User experience

User files and directories will no longer be unintentionally deleted when a custom build path is provided using the --o/--output parameter. If the output_path/<ta_name> directory already exists, users must explicitly pass the --overwrite flag to allow it to be overwritten.
