Daily snapshot builds through Jenkins

[Vinod Kone <vi...@apache.org>]

Hi there,

We would like to automate publishing of Mesos snapshot jar to
repository.apache.org through a Jenkins job in builds.a.o. Right now we do
this manually through a script
<https://github.com/apache/mesos/blob/master/support/snapshot.sh>.

I have couple questions that I was hoping you could help me with.

1) IIUC, all Jenkins build agents already have required credentials
configured in "~/m2" to be able to push to snapshot repo of RAO when doing
`mvn deploy`. Can you confirm if that's the case? Do we have to set
anything in the PATH for this to work?

2) Our POM file
<https://github.com/apache/mesos/blob/master/src/java/mesos.pom.in#L117>
uses GPG signing through maven gpg plugin. Do the Jenkins agents also have
pre-configured GPG keys or do we have to inject them somehow (any
examples?) or should we disable signing for snapshots?

Thanks,
Vinod
