slave-agent.jnlp stored in location not served by jenkins

[minid33]

Hey, I'm trying to get jenkins-mesos to work with my mesos cluster.
I was also having problems with starting dockers, there seems to be no logs at all for this issue, so I'll skip it for now.

I'm running mesos 0.20.0, Marathon 0.7.0 RC4, Jenkins 1.580 and a mesos-snapshot build (which i was hoping would have some fixes to my problems:) 0.5.0-SNAPSHOT (private-09/21/2014 21:59-minid33)

When I try to create a none-docker mesos task using the default slave info I see the following error:

It appears that the .jnlp is placed in a location that is not served by jenkins. The slave.jar file is placed inside the /tmp/mesos/..././././././...../ directory and I can curl it but I never manage to retrieve the jnlp.

Looks like the JNLP requires some authentication credentials? You could pass your auth credentials via the JVM args. See #40

[minid33]

Yep this is correct, @vinodkone 👍 perhaps this is something that should be documented but otherwise working

[vinodkone]

Would you be up for sending a PR for the README about the authentication credentials?
