Had Pipeline Job Plugin 2.25.

Our jobs have properties([...., compressBuildLog(), ...]) enabled.

Upgrade to 2.31 along with a lot of dependencies.

With the new plugin, the build console shows the output as long as the build is running. When the build is finished, there is no console anymore for a build (neither default /job/<jobname>/job/<branchname>/<buildnumber>/console nor .../consoleFull or .../consoleText ).

Remove compressBuildLog() from properties, run a build --> issue is gone for the new build. Of course, for the builds which had compressed build logs, the issue persists.

Looks like the new console view does not work with compressed build logs.

Setting to Critical as this should be mentioned at least in the upgrade notes. I don't have a chance from Classic Jenkins UI to view the logs anymore.
