问有人知道如何在$CIRCLE_BUILD_NUM中跨不同的作业使用CircleCI吗？

EN

- run:
    name: Create unique build identifier
    command: |
        GIT_SHA=$( git rev-parse --short HEAD )
        echo "export GIT_SHA=${GIT_SHA}" >> "${BASH_ENV}"

        # the always-increasing counter, based on CIRCLE_BUILD_NUM
        BUILD_COUNTER="${CIRCLE_BUILD_NUM}"
        echo "export BUILD_COUNTER=${BUILD_COUNTER}" >> "${BASH_ENV}"

        # the build identifier, which includes the short git sha
        BUILD_NUMBER="CIRC${BUILD_COUNTER}-${GIT_SHA}"
        echo "export BUILD_NUMBER=${BUILD_NUMBER}" >> "${BASH_ENV}"

        # output build id and counter
        echo -e "\nbuild counter: ${BUILD_COUNTER}; build id: ${BUILD_NUMBER}\n"
