Error updating extensions after upgrade to dockerized XWiki 17.10

Help / Discuss

Hi.

Trying to upgrade dockerized XWiki 16 to 17.10.4 I encounter errors during the last step of the distribution wizard: The extension updater shows a NoClassDefFoundError for StringUtils (and seems to abort at this point since the distribution wizard restarts during next login).
The same error is shown when running Administration>Extensions>Updater. (see screenshots)

Any ideas what’s wrong here? Did I miss an important step for the upgrade?

The error message as such is similar to the one reported here - but creating pages works fine for me: StringUtils Error creating page

Thanks for your help!

I thought the issue could be with the contrib favorites extension which would still have a dep on commons lang 2.x (GitHub - xwiki-contrib/application-favorites: Adds the concept of favorite pages · GitHub). But I’ve checked and version 1.4.1 of it depends on commons lang3, so not sure what is the problem.

Maybe @tmortagne has an idea?

According to the stack trace, the problem is in the pypi extension. Anyway, my understanding is that this extension is not really working anymore because it relies on a legacy version of the pypi protocol, so you might want to uninstall it.

Gotcha. I could finally fix the issue by uninstalling several python-extensions that triggered the same error one after the other. Apparently, the system is running fine now.

Thanks a lot for your support, @vmassol and @tmortagne !
