I have no idea why my unstable or failed builds are generating double logs, after a bit of investigation found that Build Failure Analyzer plugin is doing the trick so went to system configuration page (Manage Jenkins -> Configure System) and tried to uncheck “Convert knowledge base” and “Send notifications to Gerrit-Trigger-plugin”, once uncheck I saved my Configure System page but what I found that after saving configuration the uncheck “Convert knowledge base” again got enabled.
Any idea what’s going wrong here, for time being I disabled my “Build failure Analyzer” plugin to make the logs stable.
Attaching screen shot for your reference.
