jenkins升级踩坑记录

1. 直接用java 1.8版本启动最新版jenkins.war，直接失败

2. 下载java 11启动，依然失败，换成java17版本可以启动，但会报错

解决报错1：

一堆的插件错误，解决办法，将Jenkins目录下的config.xml文件重命名

解决报错2：

 新版本的jenkins已经使用了比11更高版本的java，而ruby-runtime插件不支持java11导致

解决办法：

进入jienkins plugins目录，删除2个部分，或者重命名ruby-runtime

rm -r ruby-runtime

rm ruby-runtime.jpi

解决升级plugin的问题：根据提示，将所有的不符合要求的plugin全部升级，重启jenkins，这个过程可能要不停地重启jenkins，再升级，再重启，不能用的插件要删除，不安全的插件要删除

解决config.xml还原：对比新的config文件，将版本改下，其余继续保留原来的配置即可继承原有的config了。
