ERROR uninstall SonarPython

SonarQube Server / Community Build Plugin Development
1

Hi,

I updated SQ from 7.9 to 8.1 and Enterprise edition, and the server is UP.
I can install and uninstall application without problems, but I have one problem with SonarPython plugin.

If I uninstall SonarPython the server is down, I can’t get up the server.
I have the next error on web.log

Someone know where is the problem?

King regards.

Hi,

The problem is that SonarQube Enterprise Edition 8.1 embeds another plugin which depends on the python analyzer.
Indeed, that’s not a good user experience and we should prevent such scenario.
We created SONAR-12993 to track the problem.

Were you able to recover your SonarQube server? Do you need any help with that?

Hello, we are currently experiencing exactly the same issue. Can you advise on how to recover our SonarQube server?

Kind regards.

We were able to resolve the issue by downloading a fresh copy of 8.1 and copying over the plugins shipped in the archive to our extensions/plugins directory.

Kind regards.

So we’re trying to evaluate SonarQube with the docker image. Uninstalling unneeded plugins seemed like a good idea. Now we’re wasting time because of this, I suppose my Docker container is now unusable and I’ll need to restart from scratch…

PS: the same problems happens with PHP
