And if these deps are version > specific, that this be encoded into the rpm requires? The failure itself originates from Tycho, and on the OSGi side versions are consulted. This particular error is a little nasty though. What happens is projects will specify foreign plugins using the "plugin" statement, and the build will lock onto the exact version that was resolved (eg. 3.3.0). The feature gets packaged and installed having a hard dependency on that exact version. When the bundle gets updated in Fedora, and the feature is used as part of a build, it won't resolve. I've always looked at this as more of an upstream problem because it's wrong to use the "plugin" statement to specify a dependency that exists outside of the actual project. I went into the issue and reasons why it's happening : https://rgrunber.wordpress.com/2014/12/17/improving-eclipse-platform-stability-on-rawhide/ This used to happen a lot in the platform, so we ended up patching it to avoid these kinds of build failures : http://pkgs.fedoraproject.org/cgit/eclipse.git/tree/eclipse-feature-plugins-to-category-ius.patch tl;dr A rebuild of eclipse-rse will definitely fix this though try removing the "plugin" definition of org.apache.commons.net because I already see there is proper requires on it in the feature. That should stop future updates to commons.net from failing the build.
