It's easily doable. In releng.aggregator repo calling `mvn clean verify -Dnative=gtk.linux.%{eclipse_arch}` should do the trick if you have all devel packages properly installed and JAVA_HOME properly set.

The problem is that different distributions have different names for packages and differ even more when we speak about devel packages.
As you said you want to build for Fedora only - doing `yum-builddep eclipse` will do the trick. We tried to keep this information in the wiki prior to CBI. But the only viable way we found was recommending installing the build requirements for the package in the distribution. Note that the natives shipped with eclipse.org downloads are built on hand crafted machines so they are everything else but not standard.

It's probably worth migrating some part of the now-dead eclipse-build to cbi if we have an agreement that best way forward is depending on people knowing their distribution for defining the dependencies.
There is a very old bug about adding autotools build to swt [1] but it's not like it gets a lot of interest. Building the natives is an effort we spend significant amount of time on improving so I would dare to recommend looking at Fedora eclipse.spec [2] for patches applied, build requires and etc.
If you're interested in working on this area let us know and we can setup a call with interested parties to see how to proceed. Up to now there wasn't much interest so it evolved around IBM's internal build system (used for eclipse.org builds) and Fedora/RHEL RPM builds needs.
