Jenkins任务批量修改的技巧分享

import jenkins.model.Jenkins
import hudson.model.Job
import jenkins.model.BuildDiscarderProperty
import hudson.tasks.LogRotator
// 遍历所有的任务
Jenkins.instance.allItems(Job).each { job ->

if ( job.isBuildable() && job.supportsLogRotator() && job.getProperty(BuildDiscarderProperty) == null) {
 println " \"${job.fullDisplayName}\" 处理中"

 job.addProperty(new BuildDiscarderProperty(new LogRotator (2, 10, 2, 10)))
 println "$job.name 已更新"
}
}
return;

/**

LogRotator构造参数分别为：
daysToKeep: If not -1, history is only kept up to this days.
numToKeep: If not -1, only this number of build logs are kept.
artifactDaysToKeep: If not -1 nor null, artifacts are only kept up to this days.
artifactNumToKeep: If not -1 nor null, only this number of builds have their artifacts kept.
