  //设置同步API超时
  --apiTimeout number
        Set timeout for asynchronous API requests.

  //设置分析器支持的格式，如拓展名，前缀等。
  -A, --analyzer (.ext|prefix.):(-|analyzer)
        Associates files with the specified prefix or extension (case-
        insensitive) to be analyzed with the given analyzer, where 'analyzer'
        may be specified using a class name (case-sensitive e.g. RubyAnalyzer)
        or analyzer language name (case-sensitive e.g. C). Option may be
        repeated.
          Ex: -A .foo:CAnalyzer
              will use the C analyzer for all files ending with .FOO
          Ex: -A bar.:Perl
              will use the Perl analyzer for all files starting with
              "BAR" (no full-stop)
          Ex: -A .c:-
              will disable specialized analyzers for all files ending with .c

  //指定ctags路径
  -c, --ctags /path/to/ctags
        Path to Universal Ctags. Default is ctags in environment PATH.

  //指定canonicalRoot路径
  --canonicalRoot /path/
        Allow symlinks to canonical targets starting with the specified root
        without otherwise needing to specify -N,--symlink for such symlinks. A
        canonical root must end with a file separator. For security, a canonical
        root cannot be the root directory. Option may be repeated.

  //检查索引
  --checkIndex
        Check index, exit with 0 on success,
        with 1 on failure.

  //指定OpenGrok数据生成的路径
  -d, --dataRoot /path/to/data/root
        The directory where OpenGrok stores the generated data.

  //指定代码仓扫描目录深度，默认为2
  --depth number
        Scanning depth for repositories in directory structure relative to
        source root. Default is 2.

  //不使能
  --disableRepository type_name
        Disables operation of an OpenGrok-supported repository. See also
        -h,--help repos. Option may be repeated.
          Ex: --disableRepository git
              will disable the GitRepository
          Ex: --disableRepository MercurialRepository

  //节省磁盘空间，OpenGrok不产生和保存超文本交叉引用文件等。
  -e, --economical
        To consume less disk space, OpenGrok will not generate and save
        hypertext cross-reference files but will generate on demand, which could
        be slightly slow.

  -G, --assignTags

  //使能历史信息
  -H, --history
        Enable history.

  --historyThreads number

        Assumes -H/--history.

  --historyFileThreads number
        The number of threads to use for history cache generation when dealing with individual fil                                                                                                        es.

        wildcards (example: -I '*.java' -I '*.c'). Option may be repeated.

  -i, --ignore pattern
        Ignore matching files (prefixed with 'f:' or no prefix) or directories
        (prefixed with 'd:'). Pattern supports wildcards (example: -i '*.so'
        -i d:'test*'). Option may be repeated.

  -l, --lock on|off|simple|native
        Set OpenGrok/Lucene locking mode of the Lucene database during index
        generation. "on" is an alias for "simple". Default is off.

  --mandoc /path/to/mandoc
        Path to mandoc(1) binary.

  -N, --symlink /path/to/symlink
        Allow the symlink to be followed. Other symlinks targeting the same
        canonical target or canonical children will be allowed too. Option may
        be repeated. (By default only symlinks directly under the source root
        directory are allowed. See also --canonicalRoot)

  -n, --noIndex
        Do not generate indexes and other data (such as history cache and xref
        files), but process all other command line options.

  --nestingMaximum number
        Maximum depth of nested repositories. Default is 1.

  -O, --optimize on|off
        Turn on/off the optimization of the index database as part of the
        indexing step. Default is on.

  -o, --ctagOpts path
        File with extra command line options for ctags.

  -P, --projects
        Generate a project for each top-level directory in source root.

  -p, --defaultProject path/to/default/project
        Path (relative to the source root) to a project that should be selected
        by default in the web application (when no other project is set either

  -Q, --quickScan on|off
        Turn on/off quick context scan. By default, only the first 1024KB of a
        file is scanned, and a link ('[..all..]') is inserted when the file is
        bigger. Activating this may slow the server down. (Note: this setting
        only affects the web application.) Default is on.

  -q, --quiet
        Run as quietly as possible. Sets logging level to WARNING.

  -R /path/to/configuration
        Read configuration from the specified file.

        with lots of renamed files. Default is off.

  --repository [path/to/repository|@file_with_paths]
        Path (relative to the source root) to a repository for generating
        history (if -H,--history is on). By default all discovered repositories
        are history-eligible; using --repository limits to only those specified.
        File containing paths can be specified via @path syntax.
        Option may be repeated.

  -S, --search [path/to/repository|@file_with_paths]

  --token string|@file_with_string
        Authorization bearer API token to use when making API calls
        to the web application

  -U, --uri SCHEME://webappURI:port/contextPath
        Send the current configuration to the specified web application.

  --updateConfig
        Populate the web application with a bare configuration, and exit.

  --userPage URL
        Base URL of the user Information provider.
        Example: "https://www.example.org/viewProfile.jspa?username=".
        Use "none" to disable link.

  --userPageSuffix URL-suffix
        URL Suffix for the user Information provider. Default: "".

  -V, --version
        Print version, and quit.
