Error while running Jenkins in Docker

Question

I am trying to run a docker with jenkins in it as below command:

docker run --rm -p 2222:2222 -p 9080:9080 -p 8081:8081 -p 9418:9418 -tivjenkinsci/workflow-demo

I continuously get below errors

INFO: Failed mkdirs of /var/jenkins_home/caches

[7412] Connection from 127.0.0.1:57701
[7412] Extended attributes (16 bytes) exist
[7412] Request upload-pack for '/repo'

I am following:
https://github.com/jenkinsci/workflow-aggregator-plugin/blob/master/demo/README.md

My configuration:

1. OS : CentOS Linux release 7.2.1511 (Core)
2. user : jenkins
3. Checked inside the docker : directory /var/jenkins_home/caches was getting created as jenkins user, having another directory: git-f20b64796d6e86ec7654f683c3eea522
4. EVERYTHING IS DEFAULT

Answer 1

So if I google that error, I find a page: https://recordnotfound.com/git-plugin-jenkinsci-31194/issues (I know, not the project you're looking at but maybe same or similar issue) and that page if you just do a text search for that error, you'll see a line:

fix logging "Failed mkdirs of /var/jenkins_home/caches" when the directory already exists

it indicates that this is an open issue and that it was logged 11 days ago albeit for a different repo. if you delete the folder does it fix the issue? Maybe monitor that bug report for a fix or log an issue against the workflow-aggregator-plugin.
