| Got it! The problem here is that we only end up throwing one exception per stage - because once we throw an exception, we're out of the stage. So if your stage has already failed before you get to post, any exception thrown by a post block never gets thrown further, because we propagate the initial exception instead. This means that the post block exception never gets logged, etc. I don't love this fix, but https://github.com/jenkinsci/pipeline-model-definition-plugin/pull/259 - with this, we'll always log when we get an exception from a post block, with full stacktrace. I'm open to changing the exact details of what we log there, but we do still want to make sure that we're throwing the first exception encountered, so that visualization can tell where the build "failed" per se. This can lead to duplicate logging if the first error of the stage is from a post block, though, which I'm not happy about. |
