We don't repackage bc bundles. The repackaging seems to be the cause of classloading issues. The original provided osgi manifest works correctly. However, version 1.57 contains an invalid BREE in its manifest which makes tycho not happy (see https://github.com/bcgit/bc-java/issues/173). Luckily 1.59 doesn't have that problem anymore. So we adjusted the pom so it uses 1.59 instead and make sure we skip repackaging and signing on 1.59. We also have to disable automatic treatment of transitive dependencies for sshj to avoid still pulling 1.57. And so we also have to manually include the other dependencies for sshj.
Use p2-maven-plugin to bundle some third-party dependencies and put them onto a p2 repository so they can be easily consumed by a tycho build.
