sdkmanager 返回相同的输出，无论传递给它的参数是什么

Question

我已经为 Windows 安装了 SDK 工具并尝试运行它；然而，不管我运行 (sdkmanager, sdkmanager --list, sdkmanager --version, sdkmanager asdoifjasodjfoas) 它总是打印相同的文本块：

Usage:
  sdkmanager [--uninstall] [<common args>] [--package_file=<file>] [<packages>...]
  sdkmanager --update [<common args>]
  sdkmanager --list [<common args>]
  sdkmanager --licenses [<common args>]
  sdkmanager --version

With --install (optional), installs or updates packages.
    By default, the listed packages are installed or (if already installed)
    updated to the latest version.
With --uninstall, uninstall the listed 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.

With --update, all installed packages are updated to the latest version.

With --list, all installed and available packages are printed out.

With --licenses, show and offer the option to accept licenses for all
     available packages that have not already been accepted.

With --version, prints the current version of sdkmanager.

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.

    --verbose: Enable verbose output.

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

我从 https://developer.android.com/studio/ 的 "Command line tools only" 部分安装了 sdkmanager。我当前的版本 Java 是 Java 9（jdk-9.0.1 和 jre-9.0.1）。

如果这意味着什么，我在使用运行程序 (java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema) 时遇到了一些问题，所以我将 sdkmanager.bat 中的 DEFAULT_JVM_OPTS 标志更改为 set DEFAULT_JVM_OPTS="-Dcom.android.sdklib.toolsdir=%~dp0\.. -XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee" 这让我运行程序没有任何错误，但也导致了这个问题的主要问题。

Answer 1

检查一次 path 变量。
我遇到了 jdk 13.

的问题

(java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema)

这并没有解决我的问题。
所以我尝试了 jdk 8 返回相同的输出，不管你提到的参数如何。
我还原了 sdkmanager 文件并设置了 path env var 并且成功了。
