We generally don't need to really build it from scratch. Most Java packages are noarch,
so they already should work on the new arch. We just need to import them and then
do proper rebuild from source when all the dependencies are satisfied.

Eclipse 4.4 is already available for Fedora 20 in Mat Booth's Copr:

shade-jar script is part of javapackages-tools and it needs objectweb-asm3-processor to work,
but javapackages-tools don't Require it (most likely to not increase install size).
