As owner or comaintainer of several packages listed above I can say that dependencies after jline are correct, at least as correct as they can be. The problem is inability of RPM or YUM to handle more complex dependency scenarios. 1) Although RPM 4.x has some (very) limited support for optional dependencies (aka "soft dependencies"), YUM doesn't understand them at all. Some of dependencies mentioned by Aleksandar are in fact optional, but I'm unable to mark them as such because of limitations imposed by YUM. 2) RPM doesn't differentiate between dependency scopes. Some dependencies may be required only in some contexts, for example only for testing, or only when using that package to compile other packages. In the latter case one would normally put these dependencies in -devel packages, but these are forbidden by packaging guidelines for Java. 3) RPM doesn't support dependency exclusions. I'm not able to express "require xbean, but without avalon" in terms of RPM requires. I don't think that the above dependency situation can be improved without removing legitimate Requires or patching upstream code. -- Mikolaj Izdebski IRC: mizdebsk -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
