Android SDK Tools 25.2.3版本(及更高版本)包含了新的工具sdkmanager，它简化了从命令行安装构建工具的任务。 它位于android_sdk/tools/bin文件夹中。

用法(来自文档):

List installed and available packages: sdkmanager --list [options] \ [--channel=channel_id] // Channels: 0 (stable), 1 (beta), 2 (dev), or 3 (canary) Use the channel option to include a package from a channel up to and including channel_id. For example, specify the canary channel to list packages from all channels. Install packages: sdkmanager packages [options] The packages argument is an SDK-style path, wrapped in quotes (for example, "build-tools;25.0.0" or "platforms;android-25"). You can pass multiple package paths, separated with a space, but they must each be wrapped in their own set of quotes.

示例用法(在我的Mac上):

alex@mbpro:~/sdk/tools/bin$ ls ../../build-tools/  
25.0.0/   
alex@mbpro:~/sdk/tools/bin$ ./sdkmanager "build-tools;25.0.2"  
done   
alex@mbpro:~/sdk/tools/bin$ ls ../../build-tools/  
25.0.0/ 25.0.2/

您还可以指定各种选项，例如强制所有连接使用HTTP(——no_https)，或者为了使用代理服务器(——proxy_host=address和——proxy_port=port)。

要检查可用选项，使用——help标志。在我的机器(Mac)上，输出如下:

alex@mbpro:~/sdk/tools/bin$ ./sdkmanager --help
Usage: 
  sdkmanager [--uninstall] [<common args>] \
    [--package_file <package-file>] [<packages>...]
  sdkmanager --update [<common args>]
  sdkmanager --list [<common args>]

In its first form, installs, or uninstalls, or updates packages.
    <package> is a sdk-style path (e.g. "build-tools;23.0.0" or 
             "platforms;android-23").
    <package-file> is a text file where each line is a sdk-style path
                   of a package to install or uninstall.
    Multiple --package_file arguments may be specified in combination
     with explicit paths.
In its second form (with --update), currently installed packages are
    updated to the latest version.
In its third form, all installed and available packages are printed out.

Common Arguments:
    --sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK containing this tool
    --channel=<channelId>: Include packages in channels up to <channelId>.
                           Common channels are:
                           0 (Stable), 1 (Beta), 2 (Dev), and 3 (Canary).

    --include_obsolete: With --list, show obsolete packages in the
                        package listing. With --update, update obsolete
                        packages as well as non-obsolete.
    --no_https: Force all connections to use http rather than https.
    --proxy=<http | socks>: Connect via a proxy of the given type.
    --proxy_host=<IP or DNS address>: IP or DNS address of the proxy to use.
    --proxy_port=<port #>: Proxy port to connect to.

* If the env var REPO_OS_OVERRIDE is set to "windows",
  "macosx", or "linux", packages will be downloaded for that OS.

灵感来自@i4niac和@Aurélien Lambert的回答，这是我想到的

csv_update_numbers=$(./android list sdk --all | grep 'Android SDK Build-tools' | grep -v 'Obsolete' | sed 's/\(.*\)\- A.*/\1/'|sed '/^$/d'|sed -e 's/^[ \t]*//'| tr '\n' ',')
csv_update_numbers_without_trailing_comma=${csv_update_numbers%?}

( sleep 5 && while [ 1 ]; do sleep 1; echo y; done ) \
    | ./android update sdk --all -u -t $csv_update_numbers_without_trailing_comma

解释

在android list sdk——all命令的结果中获得一个以逗号分隔的数字列表，这些数字是构建工具包的索引(忽略过时的包)。 保持每隔几毫秒向终端抛出'y'以接受许可证。

我尝试了这个更新所有，它工作!

echo y | $ANDROID_HOME/tools/android update sdk --no-ui

Android更新SDK

此命令将更新和安装所有最新版本的SDK工具，构建工具，SDK平台工具。

这是我的工作。

正如在其他响应中所述，构建工具需要安装——all标志。你也最好使用一个-t过滤器标志来避免安装所有的包，但是没有办法过滤所有的构建工具。

在AOSP错误跟踪器中已经有针对这两点的特性请求。请随意投票给他们，这可能会在某一天实现:
