At the end of error file,i thought may be error related to Git tool. So i have also removed git-client plugin from /var/lib/jenkins/plugins. But after that it will show error unable to read config.xml file even though file is already there in /var/lib/jenkins/config.xml

I need git-client plugin also. I don't know how to solve this problem. Please help if anyone know about this issue. Thanks

Answer 1

I met this java.lang.ArrayIndexOutOfBoundsException: -1 error before. It was because I started jenkins server with lower java version(maybe 1.6 or older?). And at the end I resolved this issue by starting jenkins with a newer version of java.

Answer 2

I stopped jenkins service and deleted that file and folder from

Jenkins_HOME/plugin
cloudbees-folder.jpi
cloudbees-folder [directory]

and then restart jenkins service.
