Jenkins Pipeline:如何转储错误？

Question

当我尝试e.getMessage()在我的管道脚本中打印errors()或转储堆栈跟踪时,我收到一条错误消息,说明不允许这样做.在这种情况下,如何将错误输出到日志？

try {
    deleteJob( JOB_NAME )
} catch (e) {
    emailError(e.getMessage())
    echo e.getMessage()
}

没有得到这个:

Answer 1

以下代码不需要 Jenkins 管理员批准异常脚本，但可用于在构建日志上打印堆栈跟踪

   catch (exc) {
      def sw = new StringWriter()
      def pw = new PrintWriter(sw)
      exc.printStackTrace(pw)
      echo sw.toString()
   }

借用了https://issues.jenkins.io/browse/JENKINS-44808?focusedCommentId=302635&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-302635的想法

呼叫签名直接在Jenkins GUI中列入白名单.转到Jenkins中的脚本批准管理页面.通常就是这样/scriptApproval/.

您应该会看到,尝试使用非白名单方法会创建"待批签名".单击method java.lang.Throwable getMessage条目旁边的批准按钮.
