 * Thrown if a {@link LocalRepoManager} could not be created for a given {@link File}, because the file

 * <p>
 * Note, that the path denotes an existing directory in the file system, though. However, it was expected
 * to be a repository and not only a simple directory. A repository contains appropriate meta-data, while
 * a simple directory does not.
