【问题描述】：
安装 android sdk 工具时出现以下错误：
java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema
为什么会发生这种情况以及如何解决？
调试输出：
$ java --version
java 9
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)
$ brew cask install android-sdk
==> Caveats
We will install android-sdk-tools, platform-tools, and build-tools for you.
You can control android sdk packages via the sdkmanager command.
You may want to add to your profile:
'export ANDROID_SDK_ROOT=/usr/local/share/android-sdk'
This operation may take up to 10 minutes depending on your internet connection.
Please, be patient.

【问题讨论】：
-
实际上这个问题是在安装 android sdk 时提出了一个合法问题
-
我遇到了这个问题，我将错误消息的第一行复制/粘贴到谷歌，这个问题是第一个出现的问题。不仅如此，下面的答案之一解决了它。这不应该完全关闭：不管问题的规则是什么，这个问题显然满足了网站的全部目的。
-
从
/Library/Java/JavaVirtualMachines删除任何早于Java 8的东西 -
在 Ubuntu 18.04 上使用包
openjdk-8-jdk和openjdk-11-jdk的 Java 8 和 Java 11 会出现问题。有谁知道为javax/xml/bind/annotation/XmlSchema安装什么，或者如何在NDK 中避免javax/xml/bind/annotation/XmlSchema？ -
这与 Java 版本无关。这是关于命令行工具的。安装命令行工具后，我通过了这个错误 Java 16。你也可以在这个问题的第二页找到正确的答案。
Android Studio -> SDK Manager -> SDK Tools -> Android SDK Command-line Tools -> Install
