Error with plugin when upgrading from 8.4 to 8.5

[Raphael_Hagi]

Hello there,

I’m trying to upgrade our EE to 8.1 to 8.5, yes… we stay a little time without updates. We starting upgrading directly from 8.1 to 8.5 but update failed, so we start step-by-step and now we get stuck on 8.4 version.

Our SonarQube are running on Kubernetes, so we stop it and start it again using 8.5 image. When it start to run, stuck with an error about problem with a specific plugin, as follows. But, before stuck with this plugin, it hangs because we use a plugin for git integration, and we disable it.

Hi @Raphael_Hagi,

Since SonarQube 8.5 the language analyzers are build-in plugins of the SonarQube distribution. You can get more information about this in the release notes.

You should remove the C-Sharp plugin, like mentioned in the log message.

Hello Malena,

Thanks for you quick reply. There is other plugins that I have to remove prior to update?

You can clean the whole folder, if you have no third party plugins installed.

Otherwise you can find a list of the bundled plugins here: https://github.com/SonarSource/sonarqube/blob/master/build.gradle#L194
All of them needs to be removed.
