jenkins - 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
实际:它会在 Poll SCM 上触发构建，也会在同一提交的“重新索引”上触发。

我们正在使用

Jenkins :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扫描。但是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
    }
