Hi Andreas. The right list for discussion Java-related stuff is debian-java@l.d.o. The lists on alioth are used for automated messages. I don't know whether you're subscribed, so I'm Cc:-ing you.

Given that Debian packages for FreeHEP ship the maven .pom files, if your upstream used maven to manage compilation and dependencies probably it would have been enough to let maven-debian-helper manage the build process. Maven is a system to describe dependencies between packages (in a descriptive format, rather than ant's imperative format) in .pom files (that use an XML dialect) and automatically build the package using data contained in .pom files. Have a look to some random freehep-* package to understand how that works from a Debian point of view. Unfortunately, your upstream decided to do things by hand. First thing to do is to send him some secret voodoo curses. The second one is decide what you want to do: given that figtree build system is not that complicated, you could choose to write yourself the .pom file and use it. The other is to patch build.xml's compilation classpath in order to have all the required JARs. In both cases you have to make sure that all the required JARs are available in the classpath when the application is launched: you have to include them in the package dependencies (maven-debian-helper can do this automatically in a shlib similar way) and add them in the execution script (by hands; don't know other options). And, of course, you also have to add build dependencies by hand. Fortunately the dependencies among FreeHEP packages can help you to reduce the number of dependencies you need to explicit. Hope to be helpful. Anyway, upstream for Java packages should really be aware of this wonderful FOSDEM talk: http://www.fosdem.org/2011/schedule/event/devpackaging I really hope slides and video to be available ASAP.
