Building spark-examples takes too much time using Maven

[Muhammad Haseeb Javed]

I checked out the master branch and started playing around with the
examples. I want to build a jar  of the examples as I wish run them using
the modified spark jar that I have. However, packaging spark-examples takes
too much time as maven tries to download the jar dependencies rather than
use the jar that are already present int the system as I extended and
packaged spark itself locally?
