当安装android sdk工具时，会产生以下错误:
java.lang.NoClassDefFoundError: javax / xml /绑定/注释/ XmlSchema
为什么会发生这种情况，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.
