@longtimeago The plexus change was supposed to give it the ability to unpack symlinks as files. This would allow the download plugin to offer that approach as an option, for those use cases where such a fallback is acceptable.

@kriegaex The permission problem is not in the plugin, but the plugin does a poor job at informing the user what’s going on, and nothing at all to help him deal with the situation. The decision to close an issue should not just consider the root problem, but also what mitigations are possible.
