Docs may need more concrete examples. If your jar is at ./app/build/libs/app.jar, then you need to have that set as the argument to artifact-list:

  artifact-list: ./artifact1.jar,./artifact2.jar

Suggested change

	cd "${PROJECT_ROOT}" && "${GITHUB_WORKSPACE}"/../__TOOL_ACTION_DIR__/create_attestation.sh
	cd "${PROJECT_ROOT}" && "${GITHUB_WORKSPACE}"/../__TOOL_ACTION_DIR__/create_attestation.sh
	mv "${PROJECT_ROOT}/slsa-build ${GITHUB_WORKSPACE}"/

move the slsa-build dir to the workspace so upload-build-dir can see slsa-build folder

[asraa]

OR just work directly from GITHUB_WORKSPACE and make sure you use PROJECT_ROOT to prefix the path

Suggested change

	cp "$path_with_version" slsa-build/"$bn"
	cp ${PROJECT_ROOT}/"$path_with_version" slsa-build/"$bn"
