Jenkins Pipeline带条件的retry步骤报错问题求助

我在Jenkins Pipeline中尝试使用带条件的retry步骤时遇到报错：

报错1：添加conditions参数时 #

WorkflowScript: 56: Invalid parameter "conditions", did you mean "count"? @ line 56, column 27.
       retry(count: 120, conditions: !Jenkins.instance.getItem('secret-name-of-job').getLastBuild().getExecution().isComplete()) {
                         ^

报错2：不指定conditions参数时 #

WorkflowScript: 56: Arguments to "retry" must be explicitly named. @ line 56, column 9.
       retry(count: 120, !Jenkins.instance.getItem('secret-name-of-job').getLastBuild().getExecution().isComplete()) {

原Jenkinsfile代码 #

steps {
  retry(count: 120, conditions: !Jenkins.instance.getItem('secret-name-of-job').getLastBuild().getExecution().isComplete()) {
    echo "Sleeping for 1 minute since e2e build is running..."
    sleep(time: 1, unit: 'MINUTES')
  } 
  // more code
}

编辑补充：成功实现的代码 #

在@ycr的帮助下，我成功实现了等待其他任务完成的功能，代码如下：

script {
  retry(count: 120) {
    if (Jenkins.instance.getItem('magic-secret-job').getLastBuild().getExecution().isComplete() == false) {
      echo "Waiting since e2e build is running..."
      sleep(time: 1, unit: "MINUTES")
      throw new Error('e2e is still running')
    }
  }
  // some_other_code
}

结论 #

• 若要在retry中使用if/循环，需将其置于script块内
• 首次创建条件时可能失败，需在“In-process Script Approval”中批准相关方法
• 需抛出异常以触发重试
• 仍不清楚conditions参数的工作机制，正如@ycr所说，它应为ErrorCondition的某种扩展
