jenkins 多分支管道中的分支索引会触发额外的构建，该构建已由 poll SCM 构建

Question

我有一个多分支管道。我在 jenkinsFile 属性中配置了触发器：

pipelineTriggers([pollSCM('H/2 * * * *')])])

多分支管道被配置为定期“扫描多分支管道触发器”。预期行为：仅在通过 jenkinsFile 配置的构建触发器上触发构建。

我们正在使用

詹金斯：2.107.1

git 插件：3.8.0

管道多分支：2.17

Answer 1

我想我们无法阻止构建触发器的扫描。但我们的构建应该能够识别并停止额外的构建。

// execute this before anything else, including requesting any time on an agent
    if (currentBuild.getBuildCauses().toString().contains('BranchIndexingCause')) {
      print "INFO: Build skipped due to trigger being Branch Indexing"
      currentBuild.result = 'ABORTED' // optional, gives a better hint to the user that it's been skipped, rather than the default which shows it's successful
      return
    }
