When listing parts in the after keyword of a part, if the listed part doesn't exist, no error will show. In core20 it was showing an error but not in core22. I believe it should show an error to help developers with potential typos. Example to reproduce: snapcraft.yaml: name: my-snap-name base: core22 version: '0.1' summary: Single-line elevator pitch description: | This is my-snap's description. grade: devel confinement: devmode parts: my-part: plugin: nil override-build: | echo "hello" my-part2: after: [trololo] plugin: nil override-build: | echo "hello" The first build runs fine. The second build properly fails. While the same example in core20 always gives: Failed to get part information: Cannot find the definition for part 'trololo', required by part 'my-part2'. Remote parts are not supported with bases, so make sure that this part is defined in the `snapcraft.yaml`.
