重置Jenkins的构建历史

1、重置单个JOB的构建历史
item = Jenkins.instance.getItemByFullName("your-job-name-here")
//THIS WILL REMOVE ALL BUILD HISTORY
item.builds.each() { build ->
  build.delete()
}
item.updateNextBuildNumber(1)

2、重置所有JOB的构建历史

Jenkins.instance.getAllItems(AbstractProject.class).each {
    item = Jenkins.instance.getItemByFullName(it.fullName)
    //THIS WILL REMOVE ALL BUILD HISTORY
    item.builds.each() { build ->
        build.delete()
    }
    item.updateNextBuildNumber(1)
}

3、重置所有JOB的构建历史

Jenkins.instance.allItems.each() { 
  item -> item.builds.each() { 
    build -> build.delete()
  }
  item.updateNextBuildNumber(1)
}
