Issue
Moving a job into a folder doesn’t preserve Unix symbolic links like lastFailedBuild, lastSuccessfulBuild, lastUnsuccessfulBuild, lastStableBuild, lastUnstableBuild in the builds folder.
Links are replaced by real folders (ref: CJP-3875).
After the move operation, you can see this exception in Jenkins logs:

After the move, Jenkins is not able to update symlink and fails with this exception:

Environment
- CloudBees Operations Center
- CloudBees Jenkins Enterprise
- Linux
Resolution
The new version 1.8.2 of the operations-center-context plugin contains the fix on broken symbolic links after a move/copy/promote operation.
The new version avoids to create new erroneous directories but it won’t repair existing broken directories.
To fix your Jenkins client master instance (on Linux):
- Upgrade the
operations-center-contextplugin to a version >= 1.8.2 - Stop your jenkins instance
- Manually delete all erroneous directories from the disk under
${JENKINS_HOME}/jobs/.- You can find them in your logs with
grep --no-filename --color -r -s "permalink" ${JENKINS_HOME}/logs/ - You can also find them on the filesystem with
find ${JENKINS_HOME}/jobs/ -type d \( -name lastFailedBuild -o -name lastSuccessfulBuild -o -name lastUnsuccessfulBuild -o -name lastStableBuild -o -name lastUnstableBuild -o -name lastFailed -o -name lastSuccessful -o -name lastUnsuccessful -o -name lastStable -o -name lastUnstable \) - You can delete all of them (ALWAYS DO A BACKUP BEFORE) with
find ${JENKINS_HOME}/jobs/ -type d \( -name lastFailedBuild -o -name lastSuccessfulBuild -o -name lastUnsuccessfulBuild -o -name lastStableBuild -o -name lastUnstableBuild -o -name lastFailed -o -name lastSuccessful -o -name lastUnsuccessful -o -name lastStable -o -name lastUnstable \) -exec rm -rfv "{}" \;
- You can find them in your logs with
- Restart jenkins which will recreate the correct symbolic links.
To fix your Jenkins client master instance (on Windows):
- Upgrade the
operations-center-contextplugin to a version >= 1.8.2 - Stop your jenkins instance
- Manually delete all erroneous directories from the disk under
%JENKINS_HOME%\jobs\.-
You can find them on the filesystem with
cd "%JENKINS_HOME%\jobs" dir lastFailedBuild /ad /s /b > dirs-to-delete.list dir lastSuccessfulBuild /ad /s /b >> dirs-to-delete.list dir lastUnsuccessfulBuild /ad /s b/ >> dirs-to-delete.list dir lastStableBuild /ad /s b/ >> dirs-to-delete.list dir lastUnstableBuild /ad /s b/ >> dirs-to-delete.list dir lastFailed /ad /s b/ >> dirs-to-delete.list dir lastSuccessful /ad /s b/ >> dirs-to-delete.list dir lastUnsuccessful /ad /s b/ >> dirs-to-delete.list dir lastStable /ad /s b/ >> dirs-to-delete.list dir lastUnstable /ad /s b/ >> dirs-to-delete.list - Create backups of directories with
for /f %i in (dirs-to-delete.list) do echo d | xcopy /f /y %i %i.bak - Verify that a copy of the directory has been created
- Delete originals with
for /f %i in (dirs-to-delete.list) do rmdir /q /s %i
-
- Restart jenkins which will recreate the correct symbolic links.
