### Bug Description craft-parts will fail if a `stage` and `prime` are defined for a part and `stage` removes a file. This can be fixed by changing [this line](https://github.com/canonical/craft-parts/blob/cdcc9dbc76e5fcf352a9744f1d1c74cfab6c15e5/craft_parts/executor/step_handler.py#L243): ```diff diff --git a/craft_parts/executor/step_handler.py b/craft_parts/executor/step_handler.py index c88b409..29e6ef8 100644 --- a/craft_parts/executor/step_handler.py +++ b/craft_parts/executor/step_handler.py @@ -240,7 +240,7 @@ class StepHandler: else: files, dirs = filesets.migratable_filesets( - prime_fileset, str(self._part.part_install_dir) + prime_fileset, str(self._part.stage_dir) ) files, dirs = migrate_files( files=files, ``` I don't know if this is on purpose, but it has been like this since it was first added to craft-parts [here](https://github.com/canonical/craft-parts/pull/59/files#diff-8b05be16f7434251a31499a62b63d4f9f2962efd02f3896a9308cbc3ab034dcfR157). source: https://github.com/canonical/snapcraft/issues/4835 from @dilyn-corner ### To Reproduce 1. Create the filetree: ``` └── src    └── foo    └── bar    ├── baz    ├── buzz    └── fizz ``` 2. Create and run the python script: ```python import logging import yaml import craft_parts from craft_parts import LifecycleManager, Step logging.basicConfig(level=logging.DEBUG) parts_yaml = """ parts: hello: plugin: dump source: src/ stage: - -foo/bar/baz prime: - foo/bar """ parts = yaml.safe_load(parts_yaml) lcm = LifecycleManager( parts, application_name="example", cache_dir=".", ) with lcm.action_executor() as aex: aex.execute(lcm.plan(Step.PRIME)) ``` ### part yaml _No response_ ### Relevant log output ```shell DEBUG:craft_parts.utils.os_utils:is_snap: False, SNAP_NAME set to None
