                    if (existing.getVersion() == null) {
                        existing.setVersion(plugin.getVersion());
                        existing.setLocation("version", location);

    @Override
    public void merge(File existing, File result) throws RepositoryException {

    @Override
    public void merge(Path existing, Path result) throws RepositoryException {
