[JENKINS-36685] Upgrade to Jenkins 2.7.1 - Jenkins will not start up #3336

Closed timja closed 8 years ago

timja commented 8 years ago

On two of our systems I have attempted to upgrade from Jenkins 1.642.4 to 2.7.1 LTS, and in both cases, Jenkins would not start up.

Here is the error message in the log:

danielbeck:

Support for the option preferredClassLoader has been dropped has it was unused at least since 1.535 or so. Remove it from your Jenkins startup script (e.g. /etc/init.d/jenkins), and it'll work again.

cliffano:

On certain installations, also look at /etc/default/jenkins .

mcsf:

Yes, I removed that from /etc/default/jenkins and that seems to have fixed the issue.

I also have an issue where when I respond to the 'Upgrade to Jenkins 2' banner, it hangs after getting (seemingly) halfway through instaling a bunch of additional plugins. I have to close the browser and reopen, whereupon the banner pops up again. The banner seems to pop up every time I log in, even after I dismiss it once. Anyhow, these seem to be separate issues so I will file separate tickets for them.
