如何轻松地使 Github 操作在特定条件下跳过后续作业执行?
How can I easily make Github Actions skip subsequent jobs execution on certain condition?
我有一个 YAML Github 动作脚本,它包含三个作业。每晚脚本应检查是否有任何用户提交(不是来自自动作业),然后执行每晚发布构建并将构建部署到测试环境。
我正在努力使用一个点,如果存储库中除了自动提交之外没有最近的提交,我可以跳过整个第二个和第三个作业的执行。
据我所知,我应该要么使脚本失败以跳过任何进一步的操作,要么将 if
条件设置为我拥有的每项工作的每一步,这看起来并不简洁。
我试图将 if
条件放在作业本身上,但它不起作用。即使 if
条件值为假,作业也会执行。如果存储库陈旧,是否还有其他更好或更优雅的解决方案来使工作失败?

根据 documentation:
When you use expressions in an if conditional, you may omit the
expression syntax (${{ }}) because GitHub automatically evaluates the
if conditional as an expression, unless the expression contains any
operators. If the expression contains any operators, the expression
must be contained within ${{ }} to explicitly mark it for evaluation.
这意味着您的 if 必须定义为:
if: ${{ needs.check-if-there-are-commits.outputs.alive == 'true' }}
