### testcraft.yaml ```yaml name: testcraft version: "0.1" base: ubuntu@24.04 platforms: a: build-on: [amd64] build-for: [all] b: build-on: [riscv64] build-for: [all] parts: my-test: plugin: nil ``` ### error ```bash craft-application/testcraft> python3 __main__.py pack testcraft internal error: AllSinglePlatformError(message='build-for: all requires exactly one platform definition (2 provided)', details='build-for: all defined in platforms: a,b', resolution="Provide only one platform with only build-for: all or remove 'all' from build-for options.", docs_url=None, doc_slug=None, logpath_report=True, reportable=True, retcode=1) ``` [full pastebin](https://paste.ubuntu.com/p/WHxprfk3Mb/) ### solution I think that craft-application could either catch and re-raise craft-cli errors or add another `except` block for craft-platforms errors [here](https://github.com/canonical/craft-application/blob/5cf3d4071569e281cf06f07a119e45659d00d3fb/craft_application/application.py#L613).
