The official 8.1 Beta server sources cannot be built - MRRC is missing dependencies needed for that.

The current workflow how customers can build the sources is:
1. get and extract Red Hat JBoss Enterprise Application Platform 8.1 Beta Source Code zip from Customer portal
2. execute ./align-dependencies.sh script so that the sources would match the EAP 8.1 Beta manifest versions
3. build the aligned sources

For ./align-dependencies.sh script to work, it seems the original state of the sources needs to be buildable too which it cannot be without all redhat dependencies of it being available in MRRC first.
