Description copied from interface: Task

A good-citizen task should execute itself responsibly: it should know what to do in case of problems: for instance, fixable or irrelevant issues should usually just be logged used the InstallContext methods, when the user can fix them later on. The task could also potentially do backups of nodes it needs to modify extensively, so the user could refer to the backups in case of problem. In the event of an unrecoverable issue, the Task could also throw a TaskExecutionException, knowing that will cancel the whole module's installation, update and startup. If a TaskExecutionException must be thrown, keep in mind that the exception message will still be shown to the end user, so try to keep them human readable.
