仅当上游管道中的工件不可用时,我才尝试触发下游管道。我正在使用 Gitlab CE v13.5.1。

这个想法是:

  1. 预构建阶段:从 nexus 卷曲并检查工件是否可用。如果是,请不要运行下游触发器,否则运行它。

    • 为了实现这一点,当 curl 失败时,我正在创建一个虚拟 exists.txt 文件,然后在后期阶段在存在条件下使用该文件。
  2. 仅当存在 exists.txt 时运行触发器。但是,问题是无论存在与否,触发器都会一直运行。也就是说,触发阶段的存在条件不起作用。

以下是 gitlab-ci 文件:

    CUSTOMER_NAME: "ABC"
    CONFIG_VERSION: "1.2.7"
    PICKER_TEMPLATE_TAG: "6.9.15"

      - "if [ '$?' -gt '0' ]; then touch exists.txt; fi"
      -set -e
    artifacts:
