I can't find any source releases so it seems like packaging a CVS tag with a build.xml generated from their pom.xml http://www.se.eecs.uni-kassel.de/~fujabawiki/index.php/Download_and_build_Fujaba_sources
Version 5.0.3 is available - a version bump would be nice. http://wwwcs.uni-paderborn.de/cs/fujaba/downloads/index.html
Version 5.0.4.1 is available. http://wwwcs.uni-paderborn.de/cs/fujaba/downloads/index.html
fujaba-4.2.0.ebuild has never been marked stable since 2008. Further, the project looks completely dead (no update since 2007). I'm in favour of last riting it.
# Patrice Clement <monsieurp@gentoo.org> (7 Jul 2015) # Upstream dead. No update since 2007. # Removal in 30 days. See bug #164536. dev-uti/fujaba 30 days timeout.
[15:49:43] [ @gentoovcs_ ] monsieurp → gentoo-x86 (dev-util/fujaba/) Remove dev-util/fujaba. See bug 164536. https://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-util/fujaba/fujaba-4.2.0.ebuild?hideattic=0&revision=1.11&view=markup Great loss for Gentoo IMHO. We won't be able to cd into Lothar's My Documents directory anymore.
