### Bug Description While building a rock for Synapse charm, there is a configuration file that should be dumped in a specific directory with a specific name by using the "organize" keyword. Its name was changed in the repository but not in the rockcraft.yaml. This went unnoticed until deploying the charm because the rock was successfully built but the file was not there. ### To Reproduce This is an example of the part that was expected to raise an error since the source file in "organize" does not exist. not-found-login_ubuntu.py is a file that does not exist. ``` synapse-conf: plugin: dump source: attributemaps organize: not-found-login_ubuntu.py: /usr/local/attributemaps/login_ubuntu.py ``` ### part yaml ```shell # Copyright 2023 Canonical Ltd. # See LICENSE file for licensing details. name: synapse summary: Synapse rock description: Synapse OCI image for the Synapse charm version: "1.0" base: ubuntu:22.04 build-base: ubuntu:22.04 license: Apache-2.0 platforms: amd64: parts: synapse: build-packages: - build-essential - curl - git - libffi-dev - libssl-dev - pkg-config - libjpeg-dev - libpq-dev - libwebp-dev - libxml++2.6-dev - libxslt1-dev - openssl - zlib1g-dev - libicu-dev - python3-dev - python3-pip - python3-setuptools stage-packages: - bash - coreutils - curl - gosu - libffi-dev - libjpeg-turbo8 - libpq5 - libwebp7 - xmlsec1 - libjemalloc2 - libicu70 - libssl-dev - openssl - python3 plugin: nil source: https://github.com/matrix-org/synapse/ source-type: git source-tag: v1.85.2 override-build: | craftctl default export RUSTUP_HOME=/rust export CARGO_HOME=/cargo export PATH=/cargo/bin:/rust/bin:$PATH export CARGO_NET_GIT_FETCH_WITH_CLI=false mkdir -p /rust /cargo /synapse /install curl -m 30 -sSf https://sh.rustup.rs | sh -s -- -y --no-modify-path --default-toolchain stable --profile minimal pip3 install -U pip setuptools pip3 install --root-user-action=ignore "poetry==1.3.2" cp pyproject.toml poetry.lock /synapse/ /usr/local/bin/poetry export --extras all -o /synapse/requirements.txt pip3 install --prefix="/install" --no-deps --no-warn-script-location -r /synapse/requirements.txt cp -r synapse /synapse/ cp -r rust /synapse/ cp pyproject.toml README.rst build_rust.py Cargo.toml Cargo.lock /synapse/ pip3 install --prefix="/install" --no-deps --no-warn-script-location /synapse[all]; cp docker/start.py $CRAFT_PART_INSTALL/ chmod 755 $CRAFT_PART_INSTALL/start.py sed -i 's/#!\/usr\/local\/bin\/python/#!\/usr\/bin\/python3/' $CRAFT_PART_INSTALL/start.py cp -r docker/conf $CRAFT_PART_INSTALL/ cp -r /usr/local $CRAFT_PART_INSTALL/usr/ cp -r /install/local/* $CRAFT_PART_INSTALL/usr/local/ mkdir -p $CRAFT_PART_INSTALL/usr/local/attributemaps chmod 755 $CRAFT_PART_INSTALL/usr/local/attributemaps synapse-conf: plugin: dump source: attributemaps organize: u1staging.py: /usr/local/attributemaps/u1staging.py ``` ### Relevant log output ```shell 2023-09-13T20:31:10.7322269Z 2023-09-13 20:31:05.623 Executed: build synapse 2023-09-13T20:31:10.7322656Z 2023-09-13 20:31:05.623 Executing parts lifecycle: build synapse-conf 2023-09-13T20:31:10.7323025Z 2023-09-13 20:31:05.623 Executing action 2023-09-13T20:31:10.7323789Z 2023-09-13 20:31:05.627 execute action synapse-conf:Action(part_name='synapse-conf', step=Step.BUILD, action_type=ActionType.RUN, reason=None, project_vars=None, properties=ActionProperties(changed_files=None, changed_dirs=None)) 2023-09-13T20:31:10.7324443Z 2023-09-13 20:31:05.628 load state file: /root/parts/synapse-conf/state/pull 2023-09-13T20:31:10.7324897Z 2023-09-13 20:31:05.635 remove directory /root/parts/synapse-conf/build 2023-09-13T20:31:10.7325894Z 2023-09-13 20:31:05.637 Executing PosixPath('/root/parts/synapse-conf/run/build.sh') 2023-09-13T20:31:10.7326621Z 2023-09-13 20:31:05.644 :: + cp --archive --link --no-dereference . /root/parts/synapse-conf/install 2023-09-13T20:31:10.7327037Z 2023-09-13 20:31:06.424 Executed: build synapse-conf 2023-09-13T20:31:10.7327436Z 2023-09-13 20:31:06.425 Executing parts lifecycle: stage pebble ```
