记一次jenkins构建失败的踩坑记录

Jenkins 构建 记录 失败 一次

核心要旨:排错要一步一步排查,一步一步确认,确认问题失败在哪一步,而不是凭空猜测错误.

本质原因是因为jdk版本升级了,之前的javahome路径失效了导致的.

但是在java升级的那天,我修改了gitee的密码,然后我从一开始就以为是因为凭证出了问题(因为在第一步就是使用凭证拉取git上的项目),然后我又看到timeout=10这种提示,以为是真的超时了(其实只是在提示超时时间值,并没有真的超时),然后又是各种搜,各种尝试跟凭证有关的东西,甚至想用sshkey来弄结果不行.

但是其实一开始排查就发现用户名和密码正确,也没有报错,但是就是构建失败,其实这个时候我还是以为拉取失败了,这一步我应该在确认了用户名密码没错并且没报错的情况下,先检查有没有真的拉取到,然后再进行判断的,而不是理所当然的猜测.

然后检查到了其实是拉取到了,跟凭证没关系,往下走发现了java找不到的异常,修改javahome之后就可以了.

正好修改gitee的密码的那天升级了java,才对认知造成了影响.

 

所以以后如果出现bug,应该一步一步按照事实和异常消息来,并且检查相关配置,而不是盲目百度和把猜测作为事实.
