jenkins 声明性管道 - 覆盖率下降时构建失败答案

【问题标题】：jenkins declerative pipeline - fail build when coverage dropsjenkins 声明性管道 - 覆盖率下降时构建失败
【发布时间】：2020-07-21 23:37:03
【问题描述】：

在Jenkinsfile 中使用声明性管道语法并使用cobertura 发布覆盖率报告，如下所示

cobertura(
  coberturaReportFile: 'coverage/cobertura-coverage.xml', 
  enableNewApi: true,
  autoUpdateHealth: true,
  autoUpdateStability: true,
  failUnstable: true,
  failUnhealthy: true,
  failNoReports: true,
  onlyStable: false
)

还尝试使用code coverage api，如下所示：

publishCoverage(
  failUnhealthy: true, 
  calculateDiffForChangeRequests: true,
  failBuildIfCoverageDecreasedInChangeRequest: true,
  failNoReports: true,
  adapters: [
    coberturaAdapter(path: 'coverage/cobertura-coverage.xml')
  ]
)

查看我能找到的所有文档，如果不使用硬编码阈值，我无法找出 what are the instructions to fail the build if coverage drops。

希望能提供参考或代码 sn-p。

【解决方案1】：

将autoUpdateHealth 与硬编码阈值结合使用即可解决问题

cobertura(
  coberturaReportFile: 'coverage/cobertura-coverage.xml', 
  enableNewApi: true,
  autoUpdateHealth: true,
  autoUpdateStability: true,
  failUnstable: true,
  failUnhealthy: true,
  failNoReports: true,
  onlyStable: false
  conditionalCoverageTargets: '80, 0, 0',
  fileCoverageTargets: '80, 0, 0',
  lineCoverageTargets: '80, 0, 0',
  methodCoverageTargets: '80, 0, 0',
  packageCoverageTargets: '80, 0, 0',
)
