Jenkins Mesos -- Error: Unable to access jarfile

I am trying to run Jenkins using dynamically generated Docker containers via mesos.

For anyone having this issue, this was caused by the mesos-slave being run from a docker container. We solved this by mounting this folder into the mesos slave:

/var/lib/mesos/slave:/var/lib/mesos/slave

That way, the files written to that directory inside the mesos slave docker also get written to the host drive.

By default, --docker_sandbox_directory is set to /mnt/mesos/sandbox, which should be a volume in the docker container that maps to /tmp/mesos/slaves/<slaveId>/frameworks/<frameworkId>/executors/<executorId>/runs/<taskId>/. Do you see slave.jar in the sandbox through the web UI? How about at the host path listed in the log? Does docker actually mount that sandbox directory into /mnt/mesos/sandbox/ inside the container? What are the permissions on slave.jar, and what user is trying to access it?
