Jenkins Git userContent插件

Question

我最近尝试在Jenkins 1.546上安装Git userContent插件.重新启动Jenkins后发生以下错误:

我尝试通过jenkins.war.bak恢复到Jenkins 1.544 ,但错误仍然存​​在.我不能再访问Jenkins了.有没有办法从中恢复,或者至少是一种不错的方式来重新安装Jenkins而不会丢失任何数据？

Answer 1

在我的情况下,这是因为我选择了git-client.jpi和git-server.jpi文件进行安装,但在Jenkins插件管理器下载之前,下载卡在数据库插件下载中.我重新启动了Jenkins,我认为Jenkins误认为尚未下载的git插件已经下载了.

要解决此问题,只需导航/var/lib/jenkins/plugins并删除导致问题的jpi文件.重启詹金斯和你的问题将得到解决.

Answer 2

当我从Jenkins禁用插件时,我遇到了同样的问题.

要删除此错误,我删除了部分禁用的插件,在我的情况下 credentials.jpi.disabled

遍历到 /var/lib/jenkins/plugins/

找到已禁用的文件,在我的例子中credentials.jpi.disabled,从插件目录中删除此文件.

重启Jenkins服务

服务jenkins重启

它工作了!!
