### Bug Description In `rockcraft.yaml`, while other `source-` part properties seem to work, `source-subdir` does not, at least when `override-build` is specified as well. ### To Reproduce With Rockcraft **_1.13.0_**, run `rockcraft pack` on the **_rockcraft.yaml_** file introduced with [this pull request](https://github.com/canonical/kubeflow-model-registry-rocks/pull/10), first by keeping the original source (which works) and then undoing the workaround of [this comment](https://github.com/canonical/kubeflow-model-registry-rocks/pull/10#discussion_r2348258259) (which gives the bug). ### Environment Rockcraft **_1.13.0_** on Ubuntu 24.04 LTS. ### rockcraft.yaml ```yaml # Dockerfile: https://github.com/kubeflow/model-registry/blob/v0.2.22/clients/ui/Dockerfile name: model-registry-ui summary: An image for the User Interface (UI) of Kubeflow Model Registry description: An image for the User Interface (UI) of Kubeflow Model Registry version: "0.2.22" license: Apache-2.0 base: ubuntu@24.04 platforms: amd64: run-user: _daemon_ services: ui: command: /bff [ --deployment-mode=kubeflow --port=8080 ] override: replace summary: "model registry ui service" startup: enabled entrypoint-service: ui parts: security-team-requirement: plugin: nil override-build: | mkdir -p ${CRAFT_PART_INSTALL}/usr/share/rocks (echo "# os-release" && cat /etc/os-release && echo "# dpkg-query" && dpkg-query -f '${db:Status-Abbrev},${binary:Package},${Version},${source:Package},${Source:Version}\n' -W) > ${CRAFT_PART_INSTALL}/usr/share/rocks/dpkg.query ui: plugin: nil source: https://github.com/kubeflow/model-registry.git # NOTE: "source-subdir" does not seem to work, but as a workaround "cd" can # be run as the first command of the "override-build" section below # source-subdir: clients/ui/frontend source-tag: v0.2.22 source-type: git build-environment: - DEPLOYMENT_MODE: kubeflow - STYLE_THEME: mui-theme build-snaps: - node/20/stable override-build: |- cd clients/ui/frontend npm cache clean --force npm ci --omit=optional npm run build:prod cp -r dist $CRAFT_PART_INSTALL/static/ bff: plugin: nil source: https://github.com/kubeflow/model-registry.git # NOTE: "source-subdir" does not seem to work, but as a workaround "cd" can # be run as the first command of the "override-build" section below # source-subdir: clients/ui/bff source-tag: v0.2.22 source-type: git build-environment: - CGO_ENABLED: "0" - GOARCH: amd64 - GOOS: linux build-snaps: - go/1.24/stable override-build: |- cd clients/ui/bff go mod download go build -a -o bff ./cmd cp bff $CRAFT_PART_INSTALL/bff ``` ### Relevant log output ```shell The expected subdirectory source is not found and the override-build commands fail. ```
