This fragment does not hold any binaries but was created to allow the manual addition of binaries. You should link binaries to the sub-directory bin/, e.g., plug-in-directory/ META-INF/ MANIFEST.MF payload/ README bin/ YOUR_EXECUTABLE Using this mechanism the plug-in should find the correct binary for your platform. !!!!! NOTE: The binaries you add manually *need* to match the version expected !!!!! by the plug-in.
