When attempting to use the dump plugin for a classic charm, I get an error indicating that validation failed due to extra fields that are not permitted. ``` $ charmcraft build Packing charm 'ceph-mon_ubuntu-20.04-amd64.charm'... Part 'charm' validation failed. - extra field 'charm-entrypoint' not permitted - extra field 'charm-requirements' not permitted Review part 'charm' and make sure it's correct. (full execution logs in '/tmp/charmcraft.log') Failed to build charm for bases index '0'. (full execution logs in '/home/wolsen/snap/charmcraft/common/charmcraft-log-_k6m7d44') ``` My charmcraft.yaml file looks as follows: ```yaml type: charm parts: charm: plugin: dump source: . prime: - actions/* - files/* - hooks/* - lib/* - templates/* - actions.yaml - config.yaml - copyright - hardening.yaml - icon.svg - LICENSE - Makefile - metadata.yaml - README.md build-packages: - python3-dev bases: - name: ubuntu channel: "20.04" architectures: - amd64 ``` If interested, the classic charm with this change is [in this repository](https://github.com/wolsen/charm-ceph-mon/tree/charmcraft) (charmcraft branch). Relevant part from the logs (below) appears to indicate that while the plugin did change to dump, the charm-requirements and charm-entrypoints are left behind with the default values. However, when validating the dump plugin does not define those as valid parameters, which causes the build to fail: ``` 2021-11-04 18:58:06,608 charmcraft.providers DEBUG Logs captured from managed instance: mm 2021-11-05 01:58:06,147 charmcraft.guard DEBUG Starting charmcraft version 1.2.1 mm 2021-11-05 01:58:06,148 charmcraft.main DEBUG Raw pre-parsed sysargs: args={'help': False, 'verbose': False, 'quiet': False, 'project_dir': None} filtered=['pack', '--bases-index', '0'] mm 2021-11-05 01:58:06,159 charmcraft.main DEBUG General parsed sysargs: command='pack' args=['--bases-index', '0'] mm 2021-11-05 01:58:06,161 charmcraft.main DEBUG Command parsed sysargs: Namespace(bases_index=[0], destructive_mode=False, entrypoint=None, force=False, requirement=None) mm 2021-11-05 01:58:06,162 charmcraft.commands.pack DEBUG Working arguments: {'from': PosixPath('/root/project'), 'destructive_mode': False, 'entrypoint': None, 'requirement': [], 'bases_indices': None, 'force': False} mm 2021-11-05 01:58:06,162 charmcraft.metadata DEBUG Parsing '/root/project/metadata.yaml' mm 2021-11-05 01:58:06,171 charmcraft.commands.build DEBUG Building for 'bases[0]' as host matches 'build-on[0]'. mm 2021-11-05 01:58:06,171 charmcraft.commands.build DEBUG Building charm in '/root/project/build' mm 2021-11-05 01:58:06,171 charmcraft.commands.build DEBUG Parts definition: {'charm': {'plugin': 'dump', 'source': '/root/project', 'prime': ['actions/*', 'files/*', 'hooks/*', 'lib/*', 'templates/*', 'actions.yaml', 'config.yaml', 'copyright', 'hardening.yaml', 'icon.svg', 'LICENSE', 'Makefile', 'metadata.yaml', 'README.md', 'src', 'venv', 'metadata.yaml', 'dispatch', 'hooks', 'config.yaml', 'actions.yaml', 'templates', 'lib', 'LICENSE', 'icon.svg', 'README.md'], 'build-packages': ['python3-dev'], 'charm-requirements': ['requirements.txt'], 'charm-entrypoint': 'src/charm.py'}} mm 2021-11-05 01:58:06,172 craft_parts.utils.os_utils DEBUG is_snap: True, SNAP_NAME set to charmcraft mm 2021-11-05 01:58:06,172 craft_parts.infos DEBUG Setting target machine to x86_64 mm 2021-11-05 01:58:06,172 charmcraft ERROR Part 'charm' validation failed. - extra field 'charm-entrypoint' not permitted - extra field 'charm-requirements' not permitted Review part 'charm' and make sure it's correct.
