bitbucket - Why is Jenkins suddenly unable to delete a workspace

Question

We have a Jenkins server which has successfully built our code over 200 times - until a couple of days ago.

We are now getting an error to indicate that Jenkins was unable to delete the workspace (full message to follow with identifying elements redacted.)

I have checked through the recent code changes, and can see nothing which may have contributed to this issue, and nothing on that server has changed for weeks.

The stack trace suggests that "the context class hudson.FilePath is missing", but the config has not been changed from the config which worked over 200 times.

Can anybody suggest steps which could be taken to fix this ?

Answer 1

I finally found the solution that explains everything.

Cause: I was using docker within Jenkins and mounted Jenkins work directory in Docker (-v pwd:/code:rw). During runtime my program generate few files that also goes in to Jenkins work directory as it is mounted. but the user is docker root not Jenkins user, because of that Jenkins user is unable to delete those files and cause this error.

Solution: you can also share Jenkins user with docker, So all file created is same as file created by Jenkins itself.

docker run --user "$(id -u):$(id -g)" -i --rm -v /etc/passwd:/etc/passwd:ro  -v `pwd`:/code:rw docker_image:tag

So Adding This basically solve the issue by Using Jenkins user inside docker.

--user "$(id -u):$(id -g)" -v /etc/passwd:/etc/passwd:ro
