In relation to my other question concerning cross-platform Tycho builds of an Eclipse RCP-based application, I have managed to get the build to produce the desired results (products including OS-specific executable launchers with the executable bits set) on a virtual machine running Xubuntu.
I have now switched from Xubuntu to Arch Linux running on a VirtualBox machine. The build works just fine, and the products are built as expected, but the executable bits aren't set anymore.
How can I configure ArchLinux for this to work correctly?
EDIT: Yes, I sudo
