void appendClassContent(String className, String value) {

  var matches =
      RegExp('class $className {.*?(^})', multiLine: true, dotAll: true)
          .allMatches(content);
  if (matches.isEmpty) {
    throw CliException('The class $className is not found in the file $path');
  } else if (matches.length > 1) {
    throw CliException(
        'The class $className is found more than once in the file $path');
