问题描述
Jenkinsfile使用k8s agent构建失败
jenkins报错截图：
查看pod app-system-23-wmx8b-5lnl2-lxvlr 的jnlp容器日志：
分析处理
一般构建失败大都是jnlp容器问题。
经以下日志分析发现jenkins主节点和slave节点的jdk版本不一致导致该提示Java JDK版本不对：
hudson/slaves/SlaveComputer$SlaveVersion has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
查看主节点jdk版本：
主节点的jdk版本为jdk11，那么slave节点jnlp镜像也应该是11版本，换成jenkins/jnlp-slave:4.13.3-1-jdk11重新构建即可
