During my update from 2.235.5 to 2.249.1 everything worked fine so far. Anyhow: This morning a few users of several Jenkins installations called me, as their Build monitor tab disappeared.

What I did:

• Create a new jenkins docker container "jenkins/jenkins:lts" (2.249.1)
• Stop the old container
• Start the new container with the linked Jenkins Homedir (08:41 PM)

I still have the old "SCM Sync Configuration Plugin" that pushes all changes to the jenkins configuration immediately to my backup GIT repository. Therefore I saw, that at 08:42PM, directly after the new Jenkins container was started, the config.xml was updated by jenkins and the build monitor plugin configuration was removed.

At this point, no plugin updates were performed, just the jenkins migration. I decided to create this issue here, as the config removal was due to the update.

Build Monitor version 1.12+build.201809061734
