Cannot delete workspace

[John Gregg]

All,

I have Jenkins 2.121.1.

I get this error when my job tries to delete the workspace:

Started by remote host 127.0.0.1
Building in workspace C:\Users\John.E.Gregg\.jenkins\jobs\Taurus\workspace
[WS-CLEANUP] Deleting project workspace...
ERROR: [WS-CLEANUP] Cannot delete workspace: C:\Users\John.E.Gregg\.jenkins\jobs\Taurus\workspace -> C:\Users\John.E.Gregg\.jenkins\jobs\Taurus\workspace_ws-cleanup_1531512476552
ERROR: Cannot delete workspace: C:\Users\John.E.Gregg\.jenkins\jobs\Taurus\workspace -> C:\Users\John.E.Gregg\.jenkins\jobs\Taurus\workspace_ws-cleanup_1531512476552

In addition, Tomcat prints this stack trace:

Jenkins is running under Tomcat started by me, so I can't understand why there could be an AccessDeniedException.  The Jenkins workspace is under my home directory.

I get the same error whether I try to delete the workspace at the start or end of my job.

thanks

I get into this problem all the time, generally due to no permission in part of the tree inside the workspace.  Most generally, I find this tends to happen when building Docker images in Linux and the workspace volume mount internals are all owned by root instead of Jenkins.

All of the Jenkins workspace deletion mechanisms need to be fixed to work in spite of permission issues. As a workaround, maybe you can coerce the build owner to modify their build to add world-everything permissions to the entire workspace...

The Windows file system will not allow a file be deleted which is held open by a process.  If a file is held open by a process, then the directory which contains that file also cannot be deleted.

I would guess that some process (probably Jenkins) has a file open in that workspace and so the workspace cannot be deleted.

Unix based file systems will allow a file to be deleted which is held open by a process.  Unix based Jenkins servers don't see this type of problem typically.

They may see problems (as mentioned by John Mellor) when file or directory permissions forbid delete.  I suspect that is not the case you're seeing here.

My preference has been to run my Jenkins server on Linux (as a Docker image) with Windows agents.  Your needs may require something different, but Linux has been a happier place to run a Jenkins server for me.
