It's a shame that ivy-local isn't available in EPEL7.
Is this because it's part of javapackages-tools and RH has an older version
packaged in RHEL7, so javapackages-tools cannot be updated?
It would be technically possible to ship updated javapackages-tools in
EPEL 7 (and even EPEL 6) - upstream supports installation on EL 6/7.
Package names would need to be different (eg. javapackages-tools4,
ivy-local4 etc.) due to EPEL policy of not overriding EL packages.
One of the biggest problem I can see is that EL 7 uses different Maven
metadata format (aka "depmaps"), while current Fedora and current
javapackages-tools use new metadata format. But there are scripts to
convert between these two formats.
If that's the case, it might be helpful if the ivy-local stuffs
could be
shipped separately for EPEL7.
That should be possible too, but would probably require more work.

I can peek at? I'm trying to get zookeeper packaged in EPEL7, but I really
don't know how to make things work without ivy-local. I'm a maven person,
and ivy is a so completely foreign to me, I'm not sure where to start. I
know it's possible to resolve locally, but I'm just not sure how to make it
work, and I learn best by example. Any help is appreciated.
Local Ivy resolution mode is not implemented in RHEL 7, but RPM builds
can patch ivy.xml to use pattern-based resolver, pointed to javadir.
Such approach is demonstrated in EL's ant-contrib package:
